This unused French postcard of Toulouse-Lautrec's "The Jocking Riding to the Starting Gate" was printed specifically for the Albi Museum in his hometown. Marked as a lithograph, the colors are nicely saturated: golden yellow in the jockey's riding pants, rich brown in the man's coat and the horse is a red-brown, bordering on maroon. "Le jockey se rendant au poteau" was originally from a 4-part race-themed series by Toulouse-Lautrec in 1899.
Since this card is unused and not postally franked, the only thing I can tell you in regard to dating it is that the publishing house of Fernand Hazan was established in 1946 in Paris and was sold to Hachette in 1992. Hazan, the Jewish son of a bookseller from Cairo, built his company into reputable art print house. Size: about 4x6 inches. In overall fine condition.
