I'll be posting on Thursday this week and next in view of where Christmas and New Year's Eve fall on the calendar, then back to the normal Saturday schedule in (gulp!) 2021.
One reason I'm moving things up is so everybody can get a stocking this year:
Topps probably ran such cross-promotions well into the 1960's while also selling their own Fun Packs and the like at various points in the year (which were roughly keyed to Valentine's Day, Hallowe'en and Christmas). They also had their own Candy Divison pumping out some holiday treats in the early 50's.
Merry Christmas everybody!
