I love vintage cookbooks from the 1940's, 1950's & 1960's. I think I like them most for the pictures that show pretty cakes and pastries displayed on vintage glassware. I picked up these vintage recipe booklets some time ago. They are a small tri-fold pamphlet with a few recipes made with Hershey products. I'm guessing they were a freebie given out to visitors of "chocolate town" a.k.a. Hershey, PA.
They were printed in 1963. The pictures showing the milk glass cake plates are my favorites.
Dainty's? A cute name for chocolate chips.
