Bill Dane (aka Bill Zulpo-Dane, born William Thacher Dane on November 12, 1938) is a North American street photographer. Dane pioneered a way to subsidize his public by using photographic postcards. He has mailed over 50,000 of his pictures as photo-postcards since 1969. As of 2007, Dane's method for making his photographs available shifted from mailing photo-postcards to offering his entire body of work on the internet.
