Often times I will received correspondence from parties looking for information about artwork on paper, so let me clear up some of the misunderstandings. There are many different types of work on paper. For instance there are original drawings, prints (which not hand signed or numbered), lithographs, serigraphs, and etchings (which are normally hand signed and numbered, but not always). There are also screen prints, block prints or woodcuts, linoleum cuts (which are normally hand signed and from an edition, but again not always) and then there are posters which usually have writing in the print on them. If you have a work on paper look for it to be hand signed, usually in pencil, and either the letters A/P (Artist Proof), E/A ( Épreuve d’artiste, the French term for Artist Proof) or a series number such as 1/100. When in doubt call a professional.
