Tomb of Edward Pilsbury (d. 1882) in St. Louis Cemetery Number Three, on Esplanade Avenue in Faubourg St. John.
Pilsbury was the 38th Mayor of New Orleans, holding the office from November of 1878 to December of 1880.
The tomb is unique for a number of reasons. It's on the end of a row of tombs, so the plot is larger than most. It's almost large enough to be a coping, but the tomb built there is just a "single." The obelisk is typical of late 19th century cemetery architecture. Egyptian themes were very popular at that time.
