Need some ideas for Yellowstone dry flies

I'm tying some dry flies for a silent auction at a FF show. Since I enjoy tying traditional dry flies, and love fishing the mountain west, I'm tying a collection of 3 to 4 dozen flies that might have been fished in Yellowstone in the 1940's or 50's. So far I've come up with the Dry Spruce Fly, the Wulff series, Sofa Pillow, Golden Stone, H & L Variant. Would like more ideas on flies unique to the area and times, like Carmichael Indispensable and Reverand Lange. Any and all suggestions appreciated.

I recall that reading that Joe's Hopper was the first of the hopper imitations. It was supposed to popular fished both as a wet and a dry fly.

Any of th patterns from Pat Barnes, Charlie Brooks, Don Martinez, Bob Carmichael.

..........and on and on

Check out the Archive of the Old Flies - I used several from the historic book, Trout Country Flies, From Greater Yellowstone Area Masters . If you type in just the Trout Country Flies in the SEARCH feature on the front/main page it should bring them all up. The recipes and history are on the same page. Have fun!
