A plain domed black sheet metal, with two metal hasps, I think it was an Aladdin or maybe that was just the little metal/glass Thermos. I wanted to be just like Dad, so I had to have the big 'safety pin' made of gas welding rod through the latches. I used it up until Jr High when it became very uncool to bring your own lunch. Stored it away and damned if my son didn't find it and used it to haul Matchbox toys, then used it for school until about the 5th grade, when it became uncool to bring your own lunch. I saw it in my son's shop the other day, it is full of pop rivets. Hillbillys are the original recyclers.
