Beginning today, at your post office, you can purchase commemorative cloud stamps. Here's more from the Postal Service's
press release:
The Cloudscapes stamp sheet includes 15 stamps based on photographs of nine cloud formations. They are arranged on the stamp pane according to altitude. Information about each cloud is on the back of the pane behind the stamp.
Yesterday, the Postal Service dedicated the stamps at a special ceremony in Boston.
When you head out to the post office this afternoon, expect sunny skies, but cool temperatures -- with highs 63-65. Tonight will be downright chilly with a low of 48 downtown and near 40 in the colder suburbs.
