 The "snarling" open mouth expression of finished big cat mounts was one of the Van Ingen's trademark qualities, a feature rigorously studied and made possible only by special head moulds which had specific built grooves on the nose area.Glass eyes were imported from Germany, hand painted individually by a factory workman each pair painted specifically for each individual taxidermy mount.Van Ingen constructed mannikins and moulds of all sizes meaning they could produce mounts of consistent quality for a variety of poses from head mounts to full mount life size pieces.
