Yeah, not 20's but... something like that. It reminded me of some I've glanced through on the net, or the old pulps that my grandad had (and were either translations from 20's pulps, or at the time cheap national copies of those. Most were cowboy stories. He just loved them. They were popular in the 50's I think); or my granduncle's, when I was a little girl (he was more into general adventure). I can't give a name of any novel for saving my life, though.
