First, this slide from "Man Of The World," Lombard's first film with soon-to-be husband William Powell. I'm guessing this to be from the United Kingdom, since there's a "Cert. A" reference and because both of these slides are being sold by someone from the UK. I also presume that the exhibitor could cover the date options that didn't apply above or below the slide to indicate when the film would be shown at that particular theater.
The second slide is from "Bolero," the first of two dance films Carole made with George Raft:
Both measure 3 5/16" square.
Bidding on each of these items begins at $5, with bids closing next Friday for both.

Here's some raw footage taken from someone being driven through Hollywood in the spring of 1932, though this is Hollywood more as movie factory town than glitz and glamour (Grauman's Chinese and Hollywood Boulevard are seen near the end). Highlights include the Charlie Chaplin studios on North La Brea Avenue and RKO on Gower Street. It's a fascinating artifact.
