I'm curious if you know where some of these were originally printed. Specifically the 14th and 17th ones down? I love these pieces and would love to display them in some way.
You have great taste! #14 is Mechanoid from 1976, and #17 is Robot Defender, part of the New Gods presentation from 1967. Neither is probably still available in a large format, but you can have full-page illos from The Jack Kirby Collector. Mechanoid is the cover of JKC #61, and Robot Defender is inside JKC #26
