Brian,
I would also go with the Bel Air Country Club, 6th tee and 5th green in the background. The topography looks right, although the bank behind the green has been leveled for a back tee for the 6th
I suspect the pictures are stills from the movie Match Play from 1930. It was about two golf pros who challenge Andy and Marjorie to a game according to IMDB. It was a comedy short starring Leo Diegel and Walter Hagen along with two actors Andy Clyde and Marjorie Beebe. The ukelele guy in the first picture is probably Clyde and the woman is Beebe. The other picture includes Hagen and Diegel. There is only one golf bag suggesting that it was a staged event, probably as part of the movie.
No, the first picture is definitely Cliff "Ukulele Ike" Edwards, Dorothy Jordan and Leo Diegel. The second picture shows the same three people but I can't tell who the caddy is, if he is anyone. I would go with Bel-Air #5 green as well.
Andy Clyde was skinny and wore a mustache and always played people who was older than he was. He is in the middle of the picture and has the tam on, which was from the short, "Match Play."
Marjorie Beebe, Leo Diegel, Andy Clyde, Walter Hagen, Bud Jamison
