Tiara Exclusives was started by Indiana Glass of Dunkirk, Indiana in 1970 as a home party selling venture like Tupperware, Mary Kay and Home Interiors. I went to my share of those parties in the late '60s and '70s. I sure do wish I still had that lettuce keeper from Tupperware. It was the green one with the white lid and a spike that stuck in the base of the head of lettuce. You remember, you slammed the lettuce down on the counter loosening up the core and after removing the core, you inserted this spike and kept it sealed in the container. It worked, too - lettuce stayed nice and fresh. Tupperware has a fancier one now with a fancier price that is beyond my means and I seriously doubt that it works any better.
