Here's some really sharp footage of Las Vegas in 1954, though there aren't many marquee signs to see. Nelson Eddy is at the Flamingo with Gale Sherwood and George DeWitt. Ms. Sherwood was the person Nelson sang with when he wasn't singing with Jeanette MacDonald, and Mr. DeWitt was the singing host of the game show, Name That Tune.
Patti Page was headlining at the Desert Inn which in this video probably looks just like it looked when my parents were married there in 1951.
