Lincoln, in fact, has been out and about a couple of times since his death. In 1901, after 36 years and several foiled grave-robbing attempts, his tomb was rebuilt and his coffin buried within several feet of poured concrete, sealing him in there for good. On that day, the crew took one last look at him, ostensibly to I.D. the president but, you have to assume, largely out of curiosity. Incredibly, the embalming process had left him completely recognizable as the man on the $5 bill.
