The French Grande Affiche is a large poster that measures around 47″ x 62″. Technically there are no bootlegs of the French Grande Affiche, however it was reprinted in the early 90’s. Many people are passing these off as original posters, so beware.
I own a rather beat up copy of this poster. You can find mint condition originals. The originals have nothing printed in either the bottom left or right corner. There is information about the printer on the bottom left side where the artwork starts. There is also nothing printed underneath the credits logo. The printer for the original poster is LaLande-Courbet.

The reprint was done by Sonis not LaLande-Courbet. Sonis did produce some original movie posters in the 70s and 80s. However, they were not the printer for original Star Wars posters. The Sonis reprint is well labeled and should show up very easily on an eBay auction page. The most glaring sign is the Sonis logo located on the bottom left corner. The Sonis printer info is located on the bottom right of the poster instead of the bottom left. Underneath the “Peter Cushing” in the credits is information about the Sonis copywrite.
Here is the poster. Notice the Sonis logo on the bottom left corner:
