Photographs by the first person to capture the image of a single snowflake with a camera are up for sale in New York, at The American Antiques Show, presented by the American Folk Art Museum, through Sunday. Wilson A. Bentley, a Vermont farmer, used ground-breaking photomicrography to record the unique images, and 26 of his works are offered by exhibitor Carl Hammer Gallery. Ten images of snowflakes are priced at $4,800 each. The others show winter scenes.
