for FB I do from roughly the mid 60's to the mid 80's. Goal is to have at least one wax, one cello and one rack pack. Just need a 1970 rack pack to complete the feat from 1968 to 1984 I think.
Here is a pic of some. the 1970 and 1971 wax boxes are legit. The 1970 cello packs are fake.
In general if the card showing on the top of a cello pack or rack pack is OC the cards in that sequence (could be 5 or 7 or 18 depending on pack) will be OC
