If this photo was taken in 1890 that means that Khan of Khiva (Khoresm) in that time was Muhammad Rakhim-khan II (1845—1910) — the 11th ruler from Uzbek dynasty of Kungrats in Khivan khandom with years of his ruling 1864—1910.

The FHT aims to establish a portal for the world's falconers and other interested parties to access aspects of the sport's rich heritage by linking existing physical archives, including international private and public collections, through the medium of an electronic archive. This archive features falconry furniture, works of art, books, correspondence from leading falconers and film and photographic material for the education and interest of falconer and scholar alike. We hope that, whatever your background or interest in our sport, you may find something of value through our archive to deepen your knowledge, understanding and passion for falconry and will help us, through your support, to preserve this precious cultural heritage for future generations.
