Animal-rights activists Bob Barker and Pamela Anderson were at the Hollywood Post Office on Wilcox Ave. to show off the 44-cent stamps Tuesday.
The stamps feature likenesses of famous vegetarians.
In addition to Barker and Anderson, they include Paul McCartney, Ellen DeGeneres, Cesar Chavez, Gandhi, Natalie Portman and others.
The stamps were produced by Stamps.com, not the Postal Service, but they can be used just like any first-class stamp.
