Edward Steichen's photo "The Pond-Moonlight" sold yesterday at auction for $2,928,000, a record-setting amount. Shot in 1904, it's one of Steichen's early experiments with color photography, so it certainly has historic value. Two other copies of the photo exist - both in museums.
One of my favorite Steichen photos is of the Flatiron Building in New York. I have a poster of it tucked away somewhere. I must pull it out and have it framed. That's as close as I'll ever get to having a real Steichen. Very cool stuff, though.
