If you look closely, you’ll see that there are “nostalgic candy mixes” for each decade. Amazon, which also sells them, describes the 1950’s mix thusly:
This swell medley of sweets is guaranteed to bring you back to an unforgettable decade where Moms stayed home, girls wore poodle skirts and the boys revved the engines of their Chevys and T-birds. The milkman delivered the milk in glass bottles right to your door, and all your favorite music was played on 78’s and 45’s. Saturday morning cartoons were incentive enough not sleep in, even in black and white. You might’ve done the Bunny Hop, worn saddle shoes or spilled Kool-Aid on your dungarees. But it was all done in the 50’s and you wouldn’t change it if you could.
Yum.
