These posters were part of a lot sold in May, 2011 at Heritage Auctions. The UNCLE poster is by an artist named Allison (from the signature), and went for $84. The I Spy poster is by Gustav Rehberger, and went for $179. The Get Smart is by Mad Magazine veteran Jack Davis and went for $120. Originally, these were sold by NBC for just a few bucks, apparently. The best source I’ve seen on the posters is at the I Spy forum, where Tatia writes:
“The eleven promotional posters produced to be given to NBC’s major affiliates as decorations for parties celebrating their 1966 season premieres were Bonanza, Daniel Boone, Flipper, Get Smart, Hey Landlord, I Spy, The Monkees, Star Trek, T.H.E. Cat, The Girl From U.N.C.L.E., and The Man From U.N.C.L.E. NBC did offer the Bonanza, Get Smart and I Spy for sale for a very limited time afterwards.”
