The original Pepsi singing jingle said, and I quote "Pepsi Cola hits the spot. Twelve full ounces, that's a lot. Twice as much and for a nickle too. You know Pepsi is the drink for you."
Back in the depression days, getting twice as much cola for a nickle was really something. I loved the jingle. Didn't care much for the cola so our family stuck with Coke (or Co-Cola as these Georgians pronounce it).
I'm simply questioning the 10 oz bottle you mentioned when the original jingle said 12 oz.
From grammar school:
“
Pepsi-Cola hits the spot
Ten minutes later you’re on the pot
Push the button, pull the chain
There goes Pepsi down the drain
“
Pepsi indeed was sold in 12 oz. bottles. Age dims the memories a bit.
