Original World War 2 business industry trade magazine vintage ad for MONSANTO CHEMICAL COMPANY of St. Louis, IL.  Snapshot of a Victory Appetite.  Women plant workers.  Transparent lunch box is made of rigid, sturdy Fibestos, product of Monosanto Plastics Division.  Since contents can be seen at a glance, box does not have to be opened at war plant gates for annoying, time consuming inspection. Privileged to serve the food industry in the victory cause.  Old 1943 WW2 era propaganda magazine advertisement.  Light library stamp on the ad.  Would still display nicely matted and framed.
