It's no secret Wonder Woman barely ages, but now the superhero will be immortalized with a collection of stamps from the United States Postal Service. 

The stamps were unveiled Saturday at Comic Con in San Diego. The warrior princess of the Amazons will get a sheet of 20 stamps with four different designs, all to commemorate the character's 75th anniversary. 

The designs will depict Wonder Woman over four distinct eras: the Golden Age (1941-55), the Silver Age (1956-72), The Bronze Age (1973-86) and the Modern Age (1987-present). 

Lynda Carter, star of the hit '70s TV show Wonder Woman, helped break the news over the weekend by sending out this tweet:

It was an all-around big weekend for Wonder Woman. A revealing trailer for the upcoming movie Wonder Woman was also released at Comic Con. The three-minute glimpse at the feature-length film racked up nearly 13 million views and counting on YouTube since it was uploaded on Saturday. 

What a time to be a Wonder Woman fan! The stamps will be issued October 7, while the movie will hit theaters next summer.
