Ken Libbrect has taken literally thousands of photos of one of the world’s most intricate and fragile subjects: snowflakes.

On October 5th, 2006, the U.S. Postal Service unveiled a commemorative set of four first-class postage stamps featuring his snowflake photographs. Over three billion stamps were printed and quickly sold out for holiday mailing.
