I'm seeking information about covers illustrated by F. S. Giles of Tulsa, Oklahoma. My only example of his work is below and I know of only one other cover that he illustrated. The pistol appears to be printed on the envelope, but the saloon scene looks like it is drawn with colored pencil.

I would like to have a sense of how many different covers F. (Frank) Giles produced.

Does anyone have one or more of his covers? If so, please contact me by private message or in this thread.

Thanks.

FF
