MMM: Marvel Stamps Coming!

Make Mine Marvel: "The second installment in the Postal Service's tribute to comic book superheroes goes on sale July 26. Last year 10 characters from D.C. Comics were honored. This year Marvel Comics earns as many stamps for their heroes.

The format of the sheet is the same as last year: 10 stamps picturing bold graphic images of the heroes, and below that 10 more stamps reproducing the covers of comic books that featured them. Most of the comic book covers are No. 1 issues from the 1960s."
