This a nice Homefront "Food for Victory" vegetable storage box collection which I am parting out. You get three 1-pint and three 1-quart boxes.

Home refrigerators designed to hold more than just an ice cube tray became popular in 1941, spurring the idea of preserving frozen vegetables. The big chest freezers didn't make it into households until after the war.

Last few pictures are from internet photo archives of WW2-era posters, and are not included in the listing.
