The auctioned copy was from the Windy City pedigree collection, which got its name from being first brought to market by Chicago dealer Gary Colabuono, but the collection was actually assembled by a mailman from Uniontown, Pennsylvania who bought several #1 issues from newsstands in the 1940's. This copy was graded by CGC as NM 9.4 Off-white pages. Only two other copies of this issue are known to exist, according to CGC's census, that have graded as high as 9.0. The auctioned Marvel Comics #1 is the only 9.4 known with none graded higher.
