The 200-inch telescope on Palomar Mountain is still arguably the most famous telescope in the world. Back in the day there was no question of that as it was featured all over the place, including ads, science fiction, trading cards, and more.
Here is the only Palomar-related comic book in my collection. I don't actually know if there are any others. If anyone knows of something else, drop me an email or leave a comment.
According to Wikipedia the Treasure Chest of Fun & Facts was a Catholic-oriented comic book series that was published from 1946 - 1972. As you can see above the March 3, 1948 issue featured the 200-inch telescope on its cover. My copy is torn you can see a cleaner copy here.
Here is the 2 page pin up from the center of the comic:
The "facts" are mostly not too bad. Although the 200-inch mirror was not cast three times.
The model shown in the illustration was real. It is now on display at Griffith Observatory. That same model was in the December, 1938 issue of Popular Science Magazine. You can see it here from the wonderful Modern Mechanix blog.
Sorry for the lack of posts lately. I was traveling and just couldn't fit it in. On my flight back home I had this wonderful view of Mt. Rainier.
