Even entertainment czar Sid Grauman loved Mount Lowe! One of the early advertising cards from Grauman's Egyptian Theatre, which opened in 1922, shares with tourists the following:
Information to Tourists
You must not miss seeing the 3 Greatest Sights in California
The Orange Groves
Mt. Lowe with its observatory
"The Ten Commandments," at the Egyptian Theatre
The back side of the card (2.5" by 4.5") shows the distances from Los Angeles to outlying areas from Alhambra to Wilmington, and, of course, Grauman's Egyptian Theatre in Hollywood, highlighted in red.
