Suppose that in the early 1960s I had bought the same kind of printing press that was used by Marvel to print their comic books. Suppose also that I bought a large supply of the same paper they used, and the same ink, and the same staples. Suppose I had then carefully stored all this away.

Could I then, in 2020, print some copies of say Amazing Fantasy #15 (1962) (first appearance of Spider-Man) on my 60 year old paper with my 60 year old ink using my 60 year old printing press and staple them with my 60 year old staples, and get something I could successfully pass off as a remarkably well preserved mint 1962 comic?

Near mint copies of Amazing Fantasy #15 have sold for around $500k. If this worked, two or three of those, a few copies of Journey into Mystery #83 (1962) (first appearance of Thor, and has sold for around $200k), and some of the other Marvel books that introduced now icon Marvel heroes in the '60s (Fantastic Four #1 in 1961, The Incredible Hulk #1 in 1962), and that would be some pretty good money.
