If the Brownie Hawkeye camera I got at age ten doesn’t count as a toy, I’d have to say the metal and plastic farm set. The barn was metal. It had to be assembled by putting the tabs through slots and then bending them over.
Well, if I haven’t mentioned it before, I’m a Halloween/horror movie fanatic. My best Christmas present – and the only thing I asked for that year – was in fifth grade: A Mattel ThingMaker Fright Factory.
