Hunting trophy

A Gems (rupicapra rupicapra) is a goat-antelope found in mountainous regions of Europe.
Antelopes are known for their distinctive backward-curving horns.
They have a rough coat, which is pale to yellow-brown in summer and darker in winter, with a dark stripe running along the back. The face has a pattern of two stripes that run on both sides of the head, from the ears through the eyes to the snout.
They live in steep, rocky areas and are therefore excellent climbers.
De Gems is a protected animal species in many countries, and strict hunting regulations apply; therefore, this headgear is special.
