Man - that is outstanding work. That would look great on my mantle! Canvasbacks have always been my favorites.
I'm always a little bit in awe of people who have the talent to carve a realistic head like that. I tried it lots of times when I was younger, but the heads wound up looking more like a seagull than a duck, so I finally had to admit to no talent for it, and used Herters plastic heads on the cork decoys we made. Thanks for sharing!!!
