After measuring one of them, my posters size is actually 11 in x 17 in. I just saw Allposters.com [
http://www.allposters.com/gallery.as...ch=101&cat=101] is selling The 400 Blows (3 different art options) 11 in. x 17 in. for $19.99 (I'm guessing + tax and shipping charges). Mine (framed in a thick sturdy transparent plastic case which can be hung by itself) costs only $9.99 in Yale & $12.99 each in MOMA (one of them came out as $0.01 in the register).
Allposters also has 11 in x 17 in posters size of Belle de jour, Breathless, 8 1/2, Kurosawa (did not see Ikiru), Godard, Almodovar's masterworks, Citizen Kane etc. I will probably end up buying 11+ more [The 400 Blows, Belle de jour, Citizen Kane, Breathless, 8 1/2, In the Mood for Love, Spirited Away (can't find Graves of the Fireflies & a 11 x 17 for A.I and Ferris Bueller's Day-Off), The Bicycle Thief, Jules et Jim, Lawrence of Arabia, another one for Akira Kurosawa - that's 11]
