I inherited my grandfather's photo albums dating from 1916-1932, which I've begun scanning into my computer. They begin with his first year at the US Naval Academy, and show his progression through the Navy. He was an early Naval aviator, beginning at Pensacola in 1924. He eventually was an Admiral during WW II. A lot of the photos have descriptions on the back, but this one is a complete mystery. What the heck is going on here?
