Our original graphic art and modern art service
At Tandem Antiques we specialize in buying and selling modern art, with more than three decades of experience in the art market in Barcelona. We know that many times these pieces are part of a family legacy or have decorated a special space for years. Our goal is to help you find a new life for them, ensuring a fair valuation and a secure transaction. We focus mainly on the acquisition of original graphic works by artists such as Picasso, Miró, Dalí and Tàpies, pieces that have both economic and historical value.
Our approach is based on explaining, valuing and acquiring with transparency modern engravings, famous engravings and pieces that are part of the universe of engraving and graphic art. Over the years we have established ourselves as a reference in avant-garde graphic art, knowing how to recognize the true value behind a signature, a numbering or a technique. If you do not know what an engraving is or what is the difference between lithography and engraving, do not worry, we will explain it in detail and without unnecessary technicalities.
In addition to personalized attention, we provide our customers with a professional, fast and uncomplicated management. If you wish to sell your collection of prints or lithographs, we invite you to learn about our process. You can contact us by WhatsApp, email or through the contact form on our website. One of our experts will respond personally to assist you in everything you need. Because, when it comes to modern works of art, it is not just about selling, but about trusting those who truly understand them and value their fair price.
How we identify and purchase works of modern art
Buying and selling an original graphic work is not an automatic process: each piece has its own history, technique, state of conservation and artistic relevance. At Tandem Antiques, before carrying out any transaction, we analyze in detail whether it is a lithograph, a engravingor even a mixed technique, always with the objective of offering a correct and adequate price. For us, understanding the difference between lithography and engraving is key, as this has a direct impact on its demand and current price.
In addition to the artist and technique, we also value the print run (how many copies exist), if the work is numbered, signed or accompanied by a certificate of authenticity. For example, an engraving by Joan Miró in his mature stage can have a very different price depending on its origin and condition. Our team is specialized in detecting these nuances, which is essential if you want to ensure that your work is sold fairly.
Many customers consult us to sell famous engravings that have been in their family for years. Our priority is to offer you a direct, transparent and no small print service. We explain every step of the process: from the technical identification to the formalization of the sale and purchase. You don’t need to have all the details; we advise you throughout the entire buying and selling process.
What kind of works we buy
In Tandem Antiques we acquire various types of modern art, but we are especially interested in those pieces that are part of the original graphic work of great masters of the twentieth century. If you own engravings or lithographs by artists such as Picasso, Miró, Dalí or Tàpies, you are in the right place. These pieces, especially if they are signed, numbered or belong to limited editions, are highly sought after by our collectors and can reach a considerable value in today’s market.
We are also interested in the art of engraving in its different variants: aquatint, etchings, drypoint, serigraphs, original lithographs and multiple sculptures. The most important thing is their authenticity and level of conservation, ideally with documentation proving their origin. Although not all 20th century artists are of commercial interest to us, we do focus on those pieces that, due to their technique, author or relevance, are in demand today.
We also consider other categories such as drawings, sketches, collages or mixed media if they belong to avant-garde movements or are linked to our reference artists. If you are not sure what type of work you own, no problem: we can advise you on how to identify it correctly. Our process consists of studying each case and providing you with the correct answer. To see examples of the type of works we acquire, you can visit our specialized page.
How our purchasing process works
Our process of buying modern art is clear, direct and uncomplicated. We know that many times you do not know where to start, so the first step is to send us a photograph by WhatsApp or email and our team will evaluate if the piece is of commercial interest. If it is, we will coordinate a safe pick-up at your home.
Once the price is agreed, we make the payment in a correct way, always valuing that you feel accompanied and well advised during the process. We buy single works or complete collections, always focusing on works of modern art by famous artists, especially those with whom we work regularly.
If your work fits within our scope of interest, do not hesitate to send us photographs. We give importance to simple but effective transactions, with the aim of giving new life to that legacy that has been stored for so long. For more information, you can visit our section specialized in modern art or contact us directly from our website. We are distinguished by our experience, professionalism and passion for graphic art.
We are mainly interested in original engravings and lithographs by 20th century artists such as Picasso, Miró, Dalí and Tàpies, although we also consider other pieces such as multiple sculptures or drawings. It is essential that the works are authentic and, preferably, signed or numbered. If you have any doubts, you can review our criteria in the sections of graphic works by Picasso, Miró or Dalí.
One of our experts can advise you to identify whether your work is a reproduction or an original graphic work. We analyze aspects such as the technique used, the quality of the paper, the signature, the serial number and the provenance. It is not necessary for you to know what an engraving is or the differences between a lithograph and an engraving: we explain them step by step, without unnecessary technicalities.
In case of purchase and sale, if the piece is located in Barcelona or surroundings, there is the possibility of home collection. If the distance is an inconvenience, we organize shipments to any point of the peninsula.
