Error card collectors, here’s another error that isn’t marked in any of my price guides: Dave Hoppmann’s last name is missing an “n” on his 1961 Nu-Card card. I noticed the misspelling last week, when adding Hoppmann’s 1964 Topps CFL card to the Vintage Football Card Gallery.
For more undocumented error cards, see my previous articles on the subject. You can also search the Gallery for all of the error cards I know about. If you know of others, drop me a line.
