With a modicum of web-surfing, you can find loads of tributes to Frank Frazetta. I especially enjoyed what my longtime buddy William Stout wrote.
This site showcases a number of Frazetta's movie posters and raises a question I have. It's about his poster, which is over on that page, for The Night They Raided Minsky's. As I recall, the final version of that one was a mess of pasteovers and redos because the studio had demanded that this be changed, that be changed, etc. I saw the original painting many years ago and pieces were falling off it, though I would imagine that wherever it is today, it's been professionally restored. I also recall that some film magazine in the late sixties printed a not-great image of the "before" version which was sexier and had all the stars in different places. The image in the final version of Jason Robards was Bert Lahr then, for example, and Robards was somewhere else in the painting. Does there exist somewhere a good copy of what Frazetta originally painted?
