so many of you probably figured out i like unopened packs.
i do like my vintage unopened packs to have the series noted on the holder.
1971 is a tough year for packs since supposedly they didnt produce as many cards that year vs other years.
1971 opc is even tougher since opc production was waaay less than topps.
1971 opc packs were sold in different series #1-4
series 4 is the best series since it contains Ryan and Aaron cards.
