I love digging for descriptions of people from Tombstone, especially Doc Holliday. Here’s a good one from a book called Leadville Sketches.
“He is a thin, spare looking man; his iron gray hair is always well combed and oiled; his boots usually wear an immaculate polish; his beautiful scarf, with an elegant diamond pin in the center, looks well on his glossy shirt front, and he prides himself on always being scrupulously neat and clean. He usually talks in a very low tone…. In his pocket he always carries a beautiful, silver-mounted revolver, 45 caliber, and while talking to a stranger, his right arm restlessly wanders in that vicinity.” – (Doc Holliday as described in ‘Leadville Sketches’, 1883.)
