Aerial view of San Francisco, circa 1938

Spectacular composite view of San Francisco in 1938 made from 164 aerial photographs from the San Francisco Public Library. The interface isn’t intuitive (the zoom control is initially hidden, and when it does appear, it’s the same color as the photos, making it hard to spot—it’s in the lower center), but it’s worth muddling through. The detail on the photos is incredible.
