Oh my! I remember to have seen this lunch boxes since I was a child, never at home though. However, sometime in the 1990s I found one looking much like this, but a plastic Rubbermaid version containing also a plastic thermos looking like an old Dewar flask. Even though, I never dared to take it out of home because someone told me, "ah, a lunch box coal mine workers use" and I was then still to vain to expect others see me as a coal mine worker
