John Dillinger death mask and eyebrow hair displayed at the National Museum of Crime & Punishment, Washington, D.C. "Original Death Mask & Hair" This plaster casting was one of the originals prepared from Dillingers body at the Cook County Morgue. Purportedly, the FBI confiscated the first mold, but others were taken without their knowledge. Look closely above the magnifier box; it contains a hair from Dillinger's eyebrow recovered from the mold.
