Freeze dry heads are the best but rather pricey. They do look good though. Reproductions are somewhat cheaper and not too bad. The real heads have a lot of shrinkage and are an older technique.
The guys winning at world shows and the NWTF are all using freeze dried head off the bird killed. Then they are painting them. They look absolutely fantastic. Black Wings Turkey out of Florida is one of the best taxidermist I have ever seen when it comes to turkey. Your mount looks really good as well.
