I purchased 2 numbered prints while in Vegas 15 years ago, one was a black and white of marilyn monroe, humphry bogart, tarzan, james dean, king kong, ect. all sitting on an I-beam over new york I think.
The other was a color print of a director sitting in a chair with a megaphone, in front of him are all the people and characters from the movies he had directed probably 25 in all including John Wayne, Marilyn, batman, ET, R2D2, Rocky, marx brothers,Sinbad, Clint Eastwood, C3PO, and others.
I can't find anything on the net, you would think doing a search on I-beam and any of the peoples name along with numbered prints would turn up something, no luck. I,m sure I can't replace the numbered prints, but if I get enough info on them at least I can get an appraisal on them.

Thanks ahead of time,
Scott
