Beginning as a radio show in the early 1950s, Mr. Moon
became one of the most popular kid shows in Portland,
Oregon.
     
Mr. Moon debuted on November 16, 1953 one month
after KOIN TV went on the air, and just over a year
after television came to Portland. The show aired
until 1958.

Wearing the Mr. Moon mask was radio disc
jockey Ed Leahy (1924 – 1989).
