Proof of Purchase. They were the lil points back in the vintage days that you could send in for free stuff. Quite a few people back then, who actually kept stuff on the card still removed the POPs for mail-aways. :)

I ~still~ have a bunch of old POPs that I had been saving for free mail-away figures. Sure wish I had used them up back then :(

Please don't yell at us, Yoda's Master. ;)
I have several vintage cardbacks that I saved. Some have no POP, since BACK THEN YOU ACTUALLY GOT MAIL-AWAY THINGS FOR THE POPS!!!! Oops. I yelled, too. Sorry. :( ;)
