Frozen strawberries in syrup were packaged in a waxed box with metal ends in the early sixties.
I remember sitting on the linoleum floor in front of the console TV set with the nearly round screen, eating thawed strawberries from the box, and watching Soupy Sales on a Saturday morning.
RIP, Mr. Sales.
UPDATE: There were Roadrunner cartoons after, then American Bandstand, then the event worth waiting for -- ABC's Wide World of Sports.
