I am always skeptical about unknown (or largely unknown) photos of Booth or Lincoln. I have seen so many spurious claims. That said, with a quick look (which is all I have had time to give this image having the link just sent to me via email), I think this one has a higher possibility of being legit. Nothing right of the bat told me it's not him.

Apparently, this was once in the collection of Josephine Cobb, formerly of the National Archives. It was she who zoomed in and found Lincoln seated on the platform at Gettysburg.

So friends, what do you think? Is this JWB or not?
