Those snappy superhero stamps featuring Superman, Batman, Wonder Woman and the rest are going on sale. We’re a bit weak on our philately, but apparently the day of issue stamps are here today at the Comic-Con.

The post office is delivering superheroes in the mail.

From Superman to Wonder Woman, the Postal Service is paying homage to America’s most beloved cartoon heroes with new postage stamps released Thursday.

The new 39-cent stamps and 24-cent postal cards include tributes to Batman, Supergirl and a half-dozen lesser known heroes like Hawkman and the Green Arrow.
