This issue is a variant of Strange Tales (Marvel, 1951 series) #137 [Regular Edition].
Dr. Strange image taken from interior story.
Part 3 of 7. 1st appearance of the SHIELD Communication Center. The chase sequence, from train to car-turned-submarine vs. frogmen is strikingly similar to the one in the film THE SPY WHO LOVED ME (1977). 1st modern appearance of Dum Dum & Gabe (regular cast members in SGT. FURY AND HIS HOLWING COMMANDOS). The relationship between Imperial Hydra & Agent G pays tribute to that of Doctor Fu Manchu & Fah Lo Suee, or The Yellow Claw and his niece, Suwan.
Part 8 of 17.
Letters from Joe Hartlaub, Michael Woodhead, Michael Arden, Jr.; includes The Mighty Marvel Checklist and an order blank for the M.M.M.S.
