New documentary probes whether Abraham Lincoln’s deathbed photo is actually him

What would Honest Abe say — is this death photo of him that went unnoticed for 150 years real or fake?

The image is eerie — with all the Lincoln trademarks, the gaunt face and famous beard. The right eye is slightly bulging, indicative of some disfigurement — or wound.

Some experts say it’s a long-lost picture of the country’s 16th president, Abraham Lincoln, taken hours after he was fatally shot by John Wilkes Booth on April 15, 1865 — and they call it a priceless historic find. The original ambrotype image is locked in an Illinois safe deposit box.
