Mammoth Annual # 9

Mammoth Annual #9 exhibits symptoms of a rush job.

For one thing, it is misnumbered as #8.

For another, it is the first of the Mammoth or Gigantic Annuals to sport an original DC cover (by Curt Swan and George Klein from Action Comics #348, March 1967) and not an original Australian cover.

The advertisement date code on the on inner back cover is KGM.M.1068

My copy contains the following rebound issues:

Superman Supacomic #109, September 1968

Super Adventure Comic #34, September 1968

All Star Adventure Comic #52, August 1968
