My first deer head was done in 1966, back when they used a wood form and shaped it with plaster paris before stretching the cape over it. After about 30 years the old boy started looking pretty ratty...had the rack remounted with a new cape, looks great.
I've got about 4 different Taxidermists that do much of my work. Prices have ranged from $150-to-$350 for a shoulder mount. Some of the more expensive mounts do look that much better. Probably have close to 40+ mounts at home and at the farm (our Hunting Lodge). Everything from Buffalo, Antelope, Mulies, Whitetails, Sheep, Ducks, Pheasants, Fox, Coons, and more. I prefer many of my mounts with a habitat scene...one is a Red Fox jumping on a rooster Pheasant in the snow, all in a coffee table display case.
Some of the best work I've seen is by "Jonas Brothers" in Denver,....their work on African and North American species is superb. For many, spending $3000-$5000 for a full stand up Grizz mount will be out of the question....but we have one in our clubhouse done by Jack Jonas, excellent workmanship.
