Technically I would not have carried a lunch box to work, not as a gainfully employed woman. I presume I would have eaten lunch in the employee cafeteria or brought my tunafish popovers to eat in a nearby park. (This is from a scene in one of my all-time favorite movies, The Devil And Miss Jones.) I believe people never ate at their desks, which is what I do most days. But let's imagine I work in a factory or a store and I can't afford to eat in the cafeteria. I've been looking for a fairly clean 1930s or 1940s lunch box, ideally something with a useable thermos. No luck yet, mostly because I'm still learning how to date those things and I really don't want to end up with something from the 1950s by mistake. I'm trying to figure out whether the classic dome-top metal boxes were actually around during the golden era. It seems to me that the picnic-basket style lunch boxes (oval or square) were mostly used by children. So now, what should go inside such a lunch box? How would you wrap the food to transport it to work?Would I bring a sandwich wrapped in wax paper? A slice of cake? Fruit? I've never seen anything in period magazines on preparing lunch for one's husband, and I'm a bit stumped. Did they have soup thermos containers? Maybe a hard-boiled egg or a potato?
