Undead fencer

 When poking about in cemeteries, one will frequently find stones with a birth date but no date of death. Generally it's the result of one spouse dying before their mate or some other family-related circumstance. What you generally don't find is an individual grave whose eventual resident is still alive, and what is likely exclusive to this particular tombstone is the fact that the yet-living memorialized is apparently so dead set (pun intended) on making sure that everyone who passes by his grave knows that he is a fencing enthusiast that he has added a portrait of himself in full regalia well in advance of his passing.
