Marvel is bringing back a 70s-era program for its Legacy initiative.

The publisher is resurrecting Marvel Value Stamps for readers that might be nostalgic for the Bronze Age of comics. The stamps feature Marvel characters and will appear on inserts in the regular cover editions of the first issues in the Marvel Legacy titles. A total of 53 new Marvel Value Stamps will be printed.

Marvel Value Stamps were printed on the letters pages of various Marvel titles between 1974 and 1976. Fans could clip them from the comics (thus devaluing a whole lot of Bronze Age books) and put them in collector’s booklets that could be ordered from the publisher. The first series included 100 stamps, and the second was comprised of 10.
