Here are three artifacts from the 1970 Comic Art Convention in New York. At above left is a poster designed by artist Gray Morrow. As I recall, the drawing was one Morrow had done when auditioning a year or two earlier for the job of drawing a proposed Medusa comic book for Marvel. (For those of you not up on this stuff: Medusa is the lady with the hair.) He didn't get the gig. It went to another artist and when Stan Lee didn't like what that guy drew, they rejected his pages and had the pilot issue instead drawn by Gene Colan…and then they scrapped the entire project. Anyway, the most interesting thing about Morrow's poster is probably the cost of admission to the convention: $1.50. I think that was a buck and a half per day but it's still a pretty low price, even for 1970.
At above right is the cover of the program book — a drawing of the Sub-Mariner by his creator, and one of the con's two Guests of Honor that year, Bill Everett. The other was Carmine Infantino. And below is an ad which ran in the program book…a piece I don't recall ever seeing anywhere else. It was penciled by Sal Amendola and inked by Dick Giordano. Pardon the fuzziness in the center where the book wouldn't lie flat on my scanner. (Marvel had an ad in the book that year too but they didn't do anything special for it.)
