Hi Barbie! Postal service releasing Barbie stamps

(CNN) - The U.S. Postal Service is releasing a new series of postage stamps featuring Barbie, which go on sale Saturday.

The stamps depict the doll in 10 different career outfits. Barbie has represented more than 250 careers since her introduction in 1959.

The new stamps are a third taller than standard commemorative stamps. The design team used bright colors, including classic Barbie pink, to capture what they described as “a spirit of fun.”
