IBM electric typewriter exhibit

Caption, "World's Fair, N.Y Visitors to IBM's World's Fair Pavilion type a free postcard on one of ten colorful IBM "Selectric" electric typewriters at the contemporary Typewriter Bar located at the Pavilion entrance. The IBM Selectric is a radically different kind of typewriter, having no type bars or movable carriage. Instead of type bars found in conventional typewriters, the machine employs a single sphere shaped typing element bearing all of the alphabetic characters, numerals and symbols."
