Not a Depression era kid, but the neighbor always gave us double yolked turkey eggs because they couldn’t be sold commerically but were perfectly fine for baking with. I would sneak some out of the kitchen and let them dry out. The dried insides stuck to one side so when rolled on the floor, they’d wobble. Fun times! I still have a shoebox of them after all these years... yeah, I know.
HA! oh the days before Nintendo, Wii, and cell phones!
