Vintage 1960s Birds Eye Food Boxes LOT Unused Flat

Description

Three unused, factory-flat 1960s Birds Eye food boxes. These particular boxes were factory-runs/testers and never hit the actual marketplace but served as the templates and test-runs for later finalized boxes.
Cosmetically, these are quite nice and display-worthy. They are vintage so, not perfect but again, quite nice. Some factory markings in pen do appear in relatively out of the way spots if one were to fold these into shape for display or frame them. In this lot, you receive:
ONE Birds Eye Vacuum Sealed Whole Kernel Corn in Butter Sauce Box,
ONE Birds Eye Green Peas and Celery with Selected Seasonings Box
and
ONE  Birds Eye Sweet Potatoes with Brown Sugar Pineapple Glaze box
See pictures for more details. Thanks.
