Broadway in the Twenties

I've posted a lot of cartoons from previous eras, but here's some from even earlier, in the twenties. The following are from Broadway Nights in 1929.

The next few are from the November 15, 1926 issue of Broadway Breeze

Gus Edson

Not quite sure what this signature says. Don Weatherly?

L. Arson or Larson? Parody of Pathé Newsreels.

Do these last two say “Jim Navoni”?

It's too bad nobody associated with these magazines are around to confirm some of these artists. If you know more than I do, give me a ring.
