"By 1917, Abercrombie & Fitch moved to Madison Avenue and 45th Street, where it occupied an entire twelve story building. Outside a sign proclaimed "Where the Blazed Trail Crosses the Boulevard." Abercrombie & Fitch had become the largest sporting goods store in the world, as well as the most impressive. A log cabin was built on the roof, which Fitch used as a townhouse. Next to it he had a casting pool installed, where serious fishermen could sample the store's impressive collection of rods and flies. In the basement, an armored rifle range was set up. There was also a golf school, a floor dedicated solely to completely set-up camps, and a dog and cat kennel. In addition to the more standard types of outdoor goods, A&F had a selection of exotic sporting equipment that would make the imagination reel: hot air balloons, yachting pennants, portable trampolines, treadmills for exercising dogs, throwing knives, shirts of chainmail, leopard collars, and everything a person could possibly need for falconry.
Abercrombie & Fitch outfitted many great hunting and exploration expeditions, like Theodore Roosevelt's trips to Africa and the Amazon and Robert Peary's expedition to the North Pole. Ernest Hemingway bought his guns there. Presidents Hoover and Einsenhower relied on A&F for the best fishing equipment. Other famous clients included Amelia Earhart, Presidents Taft, Harding and Kennedy, the Duke of Windsor, Bing Crosby, Howard Hughes, Katharine Hepburn, Greta Garbo and Clark Gable. And there was more: Cole Porter ordered his evening clothes from Abercrombie & Fitch." During Prohibition, A&F was the place to buy hip flasks.
