Is there a master list floating around out there for errors and variations on Topps sets pre-1995 and other vintage sets pre-1980? Perhaps a link to a spreadsheet online? I've noticed an article here and an article there on some variations that aren't listed in Beckett or SCD but wondered if it was all compiled by someone in one place already. Thank you!

p.s. Not trying to start a debate on this thread about the difference between a print flaw and a variation.
