This neat, uncommon, color Japanese post card of Japanese young ladies dancing(in fine-very fine condition, but has a pin hole in its top) looks to have been sent as free-franked, military mail(written in pen in the top, right corner; w/ the officer's signature!) from Japan by a Captain Adjutant Karel Frederik Quarles van Ufford, of the Royal Dutch Artillery! He was a member of the Dutch nobility, and was most likely serving as the Dutch military attache at the Dutch Embassy in Tokyo. His father had been a diplomat. The mail arrived in The Haag, The Netherlands, on March 23, 1915. Karel Frederik Quarles van Ufford was writing his daughter, Lili Byvanck-Quarles van Ufford! She would later become an archaeologist! Karel Frederik Quarles van Ufford, himself, would later become president of International Federation for Equestrian Sports! Noted imperfections aside, this remains a very unique, example of free-franked, military mail sent from Japan by a then well-known member of the Dutch nobility, Dutch artillery officer, and horse enthusiast, Karel Frederik Quarles van Ufford!
