Photos of Revolutionary War veterans? No, it's not a hoax.

While the American Revolution took place from 1765-1783 and photography wasn't invented until the 19th century, members of the Revolutionary War generation who survived into their 80s, 90s and even 100s (some of these guys look pretty good for 102) were alive for the age of photography.

When the Museum of the American Revolution opens next year in Philadelphia on April 19, it will feature a collection of photos of those who lived through the American Revolution.

Below is a sneak peek, provided by the museum and curated from the Library of Congress and other institutions, showing America's first veterans.

Two are local guys. One went on to serve three terms in the Pennsylvania House of Representatives after fighting in the war.
