I don't imagine that there is much of Gumby on TV these days, but the entire Gumby Saga is
available on DVD and it contains some pretty interesting stuff. The very first episode of Gumby dates from 1956 and certainly qualifies as science fiction. In that episode Gumby takes a trip to the Moon --13 years before Neal & Buzz went there.
In the inaugural episode Gumby uses a toy of the Hale Telescope. Here's a short clip from the beginning of the episode that shows Gumby looking through the toy telescope.
It is a pretty cool toy, a "Mt. Palomar Telescope" made by St. Pierre & Patterson Mfg., Co, North Hollywood, Calif. As near as I can tell these were sold in the 50s & 60s. From time to time you can find one on eBay. I have a couple of these toy telescopes in my collection. I will devote a future post to these cool toy telescopes.
After Gumby looks at the Moon he rides in a toy spaceship to the Moon there he meets aliens and ultimately gets stuck there. Thankfully his parents use the toy telescope to see Gumby there (That first view of the Moon has to be rescued by his parents.
