I just posted one of the Rarest sports comic books known to exist. It is in spectacular condition and is professionally graded by CGC. It is the equivalent of a PSA 9 and is the best known copy.
Take a look when you get the chance by clicking on the RECENT ADDITIONS button on my HOME page. It is on the second page in, so click Next 25 books when you get there.
