Heritage Galleries' July auction ended this weekend with wacky 1923 Hollywood one sheet (grade: FN/VF)--I love this one!-- going for $89,625. Too bad this silent film no longer exists....
A grade FN+ Gilda went for $33,460; a grade FN/VF Broadway Melody went for $31,070; and-- a steal at $5,078.75-- was a VF Vertigo, possibly the greatest poster of all time (I'm actually glad that so many copies of it exist that, conceivably, I could own one someday!).
I was surprised that the foreign posters didn't get big numbers, per se. The Seven Samurai-- a great poster (grade: VF)-- went for $13,145.
If I were bidding, I would have had my eye on the Trader Horn poster (grade: VG/FN), which went for $11,950-- an odd but interesting poster and an underrated film.
There were many noteworthy items in this auction. Just to name one more, a lobby card from Alfred Hitchcock's Blackmail (a VERY rare item), went for $14,340.
