Library of Congress asks: Who the hell are the mystery people in these photos?

After several years of the Internet's help, the Library of Congress has narrowed down its collection of 800 photographs of mystery people from the entertainment industry down to less than 30. They've just posted some of the toughest remaining. My favorites are above and below. Who the hell are these people? If you know, post in their comments section and check out the rest: "Mystery Photo Contest: Nearing the End!"

Here's the aforementioned list of incorrect guesses (we've checked with the people named).

Meanwhile, I have inquired of, but not heard back from, the following acts, all of whom readers have suggested: 39 Clocks, Balaam and the Angel, Edn Ozn, Fashion, Faster Pussycat, Lady Wreckless, Main Street Preachers and The Cut.

LOC: "This lady with the winsome smile was probably an actress in the silent film era, or maybe in the early talkies. It's a professional head shot, so she at least got a start in the biz. But she could have been a singer, dancer, model or a regional theater actress who never got very far. Suggestions have included Jeanette Loff, Edwina Booth and Isabel Jewel. Alas, none are correct."
LOC: "The man with the camera remains a mystery to us. It's a staged photo — nice lighting! — but that doesn't necessarily mean he's a famous photographer, cinematographer or director. It could have been part of his publicity kit. He appears young, so maybe he didn't stay in the business that long. Hard to pin down the era, too, though the watch would be a clue."
