**I'm not sure but I THINK the thermos goes to the 1960s lost in space lunchbox.

This vintage Lost in Space Dome Lunchbox from 1998 comes with a matching Thermos for the ultimate retro lunch experience. The metal lunchbox features colorful graphics of the classic TV show, and the Thermos fits snugly inside to keep your drinks cool or warm. The lunchbox is a great addition to any collection of vintage memorabilia and is perfect for fans of Lost in Space. It was manufactured before 1970 and is a must-have for collectors of pre-1970s metal lunchboxes.
