Tupperware Lettuce Keeper Value Guide

The Tupperware Lettuce Keeper is a quintessential example of 1960s mid-century modern utility, designed specifically to maintain produce crispness using Earl Tupper's patented airtight seal technology. This polyethylene container gained legendary status through Brownie Wise's home party marketing, making it a nostalgic icon of American suburban history.

What affects the value of Tupperware Lettuce Keeper?

• The presence of the original internal core spike significantly increases the market value toward the $25 range.
• Overall clarity and lack of 'Tupper-scratches' or melting marks from dishwasher heat affect the final price.
• The seal integrity is vital; a lid that has warped or lost its airtight suction reduces the item's collectible worth.
• Staining from food or odors trapped in the polyethylene plastic can lower the value below the standard $20 estimate.

How to Identify Tupperware Lettuce Keeper?

• Check for the authentic Tupperware brand logo embossed on the bottom of the vibrant green polyethylene bowl.
• Verify the presence of the internal three-pronged 'spike' insert designed to hold the lettuce head in place.
• Ensure the lid features the classic translucent or matching green seal that fits the rim with a distinct airtight snap.
• Look for the specific 1960s era mold numbers typically found on the underside of the container and lid.
