From Bucknell University's history department. Check out the boy near the middle of this photo labeled Young Boys in Gettysburg. Some believe his clothes look a little too modern.
What about the guy sporting a Mohawk at left center in this undated photo? He does look a little lost.
With more photoshop savvy than I possess, even I could become a time traveler. Anyone who wants to volunteer for such a task would be full of such awesomeness, I'd have to reward the effort with a gift card of equal awesomeness. Even if it's bad, it would be oh, so good.
What's your take on the boy and the Mohawk guy?
