Unique skull of an old bison bull which has been manually coated with a real bronze layer. This very time-consuming process ensures a very special and exclusive appearance. Metallization is done by manually applying a real metal layer which is actually oxidized. This real metal layer gives the skull a high-quality appearance and makes it a true work of art... We can metallize skulls or hunting trophies for you in different metals and precious metals. Please inquire about the possibilities.
