All our antique and vintage posters, books, maps and prints are guaranteed originals as detailed in their descriptions and include a certificate of authenticity.
Practically all of the posters found on our website are lithographs. This is a method of printing that involves carving each colour of the image onto a piece of stone. The poster sheet is then imprinted consecutively with a stone slab for each colour, creating a stunning and rich image. With the exception of silk printing, I believe that other printing techniques do not deliver the same impact of colour as lithography.
