Here is an ad from 1958 introducing a new flavor of Toll House Morsels from Nestle's - Butterscotch - complete with a recipe:
And here's how they look today. They do still have a bit of plaid on the package - but I think I like the old plaid better! Now, they do have the little picture of the Toll House "Since 1939" on the front. I like that very much.
I just might need to make me some of those Scrumptious Scotchies!
