Marvel Mystery Comics 2 CGC 1939 featuring the Sub-Mariner (3rd appearance). Human Torch (2nd app), and Angel (2nd app). This one has a repro cover over a coverless copy. If you had a cover, would be much better obviously. Still, this presents great with the repro and the book inside is actually in pretty good shape. Pages are browning a bit, but not torn or anything. I tried to find a cover for a long time, you can continue the search!
