Up for sale is a nice affordable copy of a great Silver Age key issue, the one-shot Iron Man & Sub-Mariner #1, which pre-dates both Iron Man #1 and Sub-Mariner #1. Published in 1968 (now 56 years old).
This copy is a CGC 5.5 with Off-White to White pages.
Items will be securely packaged and shipped out the morning after payment is received. Please check out the many other Silver and Bronze Age keys I have listed this week (and upcoming over the next two weeks).
