Invaders #33 features a memorable battle between Thor and Namor, with a cameo appearance by Doctor Doom. Roy Thomas returns to scripting duties alongside artwork by Alan Kupperberg and Frank Springer, while Jack Kirby and Dave Cockrum provide the striking cover art. Graded CGC 8.5 with Off-White to White Pages, this copy presents exceptionally well and represents an excellent addition for collectors of the Invaders series, Thor appearances, or Jack Kirby Bronze Age work. The combination of major Marvel characters and an attractive cover helps distinguish this issue within the later portion of the run.
