I found it deeply disturbing when “lunch boxes” went from sturdy metal like that one to cheapo colored plastic. It was like a signal that something ominous, something bad was starting to occur in the culture.
Sort of like when there was a new “Tom and Jerry” cartoon show broadcast on Saturday mornings... and instead of violently trying to off each other, my God, they were presented as friendly BUDDIES!
Naturally, I blamed the liberal hippies.
Same thing happened to Itchy and Scratchy
