A lithograph is considered as a limited edition work of art. An image is therefore broken down into a number of colors to make the print. One copy is printed at a time on each sheet, color after color, over several days. Each lithograph includes the number on the print, the stamp of the lithography workshop, the stamp of Pierre Farel and his signature with a certificate of authenticity. DEDICACE: You can ask for a personalized dedication, giving the name or first names.
