I still have two Aladdin lunchboxes.
A 1964 NFL Quarterback
A 1968 Bonanza
Neither one has the thermos. They always broke because they were lined with glass. If you dropped them mom threw out the thermos.
We used to be able to buy replacement liners. I think they’re still available, but you do have to look for them.
I don’t think any of us six kids ever had a thermos last a whole week. After a while Mom just didn’t bother putting them in the lunchboxes to begin with. By about Thanksgiving the boxes themselves were pretty much destroyed, and it was paper bags after that.
After 60 years, give or take, I don’t remember the design on any of my various lunchboxes.
I still have my Batman lunchbox from the mid ‘69’s. My brother still has his Bonanza and my sister has her Mary Poppins. None of us had a thermos.
