There are currently quite a few Cartier-Bresson prints for sale on the global photography market. However, only prints signed or autographed by Henri Cartier-Bresson, and the ones he printed himself in the 1930’s, are intended to be acquired by collectors. In a letter he wrote in 2000, he clearly specified :

“I, the undersigned, Henri Cartier-Bresson, domiciliated at 198 rue de Rivoli 75001 Paris, declare what follows – I have always signed and autographed my photographs to the people I wished to give them to – all other prints, that are only identified with a "Henri Cartier-Bresson" stamp or a "Magnum Photos" stamp, belong to my own person.

Therefore, anyone in possession of such a print cannot possibly claim in good faith that he or she owns it.

Paris, 30 October 2000.”
