Paramount, more of a free-wheeling studio, was considerably different. When its stars were collected, the result was more akin to a club photo from a high school yearbook, with an air of informality. Here's an example of that tone, circa 1935:
And just look who's front and center -- none other than Carole Lombard. (Was she placed there because she was so well-liked, or because she was blonde and stood out? Probably a little of both.) Carole's wearing slacks and appears to be holding a sombrero with her right hand -- could you envision that in an MGM group shot? -- and Baby LeRoy with her left.
I can't identify everyone on hand, but among those present are Joel McCrea, Fredric March, Jack Oakie and Charlie Ruggles. If you want to try your hand at identifying, go right ahead.
Of course, you might find it easier to do if you had the photo there with you...and you indeed have that opportunity. It's an 8" x 10" reprint being auctioned at eBay; bids begin at $6 (no one has yet bid as of this writing), and bidding closes at just after 5:25 p.m. (Eastern) on Sunday. Think you're interested?
