Dan BrettaI'm not exactly sure Jeff, but I do know that many of the oldtimers used to trim their cards to fit into plastic holders and sheets....that I believe was a time when cards were collected for what they were....cards and not commodities. I don't think it would have been a problem to restore a card before the 1980s which is when I think the investment side of the hobby really kicked in.
edited to add: I think the grading companies hold the biggest sway in this hobby when it comes to what is accepted and not accepted....once they started slabbing postcards the prices of postcards shot up.
