Issued in 1938, this rare comic features the first appearance of Superman and Lois Lane. At the time of its debut, the issue cost 10 cents.
It's the only comic to have sold for more than $2 million for a single original copy. Reportedly, only 50 to 100 original copies still exist. Other than a CGC graded 2.5, this is the only known copy with "perfect white" pages.
