I'd HEARD about the famous incident when Betty Furness couldn't get the door of the fridge open and she had to ad lib by describing the interior features that the audience couldn't see. Thanks for providing it. Didn't realize they had frost-free units as early as 1953. My parents had a mid-50s GE that did have it. Bottom slide-out freezer with door activated by a pedal. The fridge shelves were semi-circular, revolved around a center post so you just rotated the shelf to retrieve any item in the back, and the shelves were fully height-adjustable up and down on the center post. It probably was made 1956-58; they were in rented housing until 1958, when they bought their first house, so the "newest" the GE could have been was 1958.
