Official Announcement The Postal Service will issue 39-cent Holiday Snowflakes special stamps in four designs, on October 5, 2006, in New York, New York (Mega Stamp Show). The stamps, designed by Richard Sheaff of Scottsdale, Arizona, go on sale nationwide October 6, 2006.

In celebration of the winter holiday season, the Postal Service will produce these four stamps featuring photographs of snowflakes. The stamps are photographs of two basic snowflake patterns by physicist Kenneth Libbrecht of Pasadena, California. The patterns are stellar dendrites, which form branching treelike arms and sectored plates, which form platelike arms.

Because fallen snowflakes start to melt and lose their shape in mere minutes, Libbrecht quickly transferred the snowflakes from cardboard to a glass slide using a paintbrush. He then snapped the photos inside a temperature-regulated enclosure using a digital camera attached to a high-resolution microscope.

The stamps will be issued in a pressure-sensitive adhesive (PSA) pane of 20 stamps (Item 568600), a double- sided booklet of 20 stamps (Item 675600), a folded vending booklet of 20 stamps (Item 675500), and an ATM sheetlet of 18 stamps (Item 569400).
