Stereoscopic full-length portrait in military uniform of Sir Madhava Rao Sindhia (1876-1925), Maharaja of Gwalior, at Lashkar in Madhya Pradesh, taken by James Ricalton in c. 1903, from The Underwood Travel Library: Stereoscopic Views of India. This image of the Maharajah, with his aides and a European official standing behind him, is described in Ricalton's 'India Through the Stereoscope' (1907): "I promised to present you to His Highness, and you are now before him at the doorway of his palatial home. He is the son of a high-born Maratha family, and was born in 1876. He received a college education at the University of Cambridge, England, and gained a degree of LL.D from that great institution. He succeeded his father the late Maharajah Sindhia in 1886. His Highness is Hon. Colonel in the British Army, special A.D.C. to King Edward, and Knight Grand Commander of the Star of India." This is one of a series of 100 photographs, designed to be viewed through a special binocular viewer, producing a 3D effect, which were sold together with a book of descriptions and a map. Stereoscopic cameras, those with two lenses and the ability to take two photographs at the same time, were introduced in the mid 19th century.
