Borjomi - hydrothermal health spa resort - Georgia
Borjomi - a hydrothermal health spa resort in the southern region of Samskhe-Javakheti in Georgia with an international reputation for its geothermal spring mineral water resources. Borjomis mineral waters were first mentioned as early as the 15th century but gained wider notoriety when the daughter of Evgeny Golovin, viceroy of the Russian Czar in the Caucasus, was cured there. The Yekaterinsky spring and the Yevgeniyevsky springs are named after them, respectively. Date: circa 1905
Portrait of Louis Wain
Portrait of Louis Wain taken from an advertisement for Phosferine, a tonic medicine, featuring Louis Wain, the famous cat artist. Wain testifies that the tonic, ...is a good pick-me-up, improves one's appetite and possesses very striking invigorating properties'. Wain was able to turn his hand to drawing a wide variety of animals prior to the fame he achieved with his feline creations. Sadly his growing obsession with cats turned to insanity and he died penniless in a mental asylum in 1939.
