That looks like the original Everlasting Gobstoppers candies, when they were jupiter-sized and you could easily choke and die on one.
you know, when child safety was not considered a thing.
from my perspective, child safety started to become a thing in the mid 70s. of course when i got to age 14, child protection kicked in for the whole culture. and everyone started being all worried about the children and they, like, banned flammable pajamas and choking hazards and stuff
it's just a shame about all the kids i grew up with who died of choking on jawbreakers, and of going to bed in flaming pajamas. and got their eyes knocked out by
clackers. all those blind, choked, burned up kids. and pegged in the head by a lawn dart, too.
