Antique slide out metal lunch pail by Universal!  This vintage metal lunchbox has a patent date of 1913!  It slides out to reveal a slot for a thermos (not included) and space for the lunch.  It is missing the original handle and is in heavily used condition (see condition description and pics).  It measures about 10" long, 4.75" deep, and 7" tall.
