In 1922, Frederic Eugene Ives and Jacob Leventhal began releasing their first stereoscopic shorts made over a three-year period. The first film, entitled "Plastigrams", was distributed nationally by Educational Pictures in the red-and-blue anaglyph format. Ives and Leventhal then went on to produce the following stereoscopic shorts in the "Stereoscopiks Series" released by Pathé Films in 1925: "Zowie" (April 10), "Luna-cy!" (May 18), "The Run-Away Taxi" (December 17) and "Ouch" (December 17). On 22 September 1924, "Luna-cy!" was re-released in the De Forest Phonofilm sound-on-film system.
