Western Illustrations

These are pictures of some Wester Illustrations that I purchased at an antique store in Reno years ago. The artist's name is Stew Walters, and he has a reno address. I'm assuming these aren't recent because the phone number doesn't have 7 digits.

I'm trying to gather any information that I can so I can establish some provenance for these drawings. If you happen to know anything surrounding these drawings(published? dates?), I would appreciate if you could send the info my way.

I can be contacted at pezcore13@yahoo.com

Thanks!
