These images of gravestones were pasted to the wall of a passageway in the West 4th Street subway station. They have a credit line (A DieKu - Nick Beef – NYC) printed in the bottom border but provide no other information about their origin or purpose.
The gravestones in the upper image follow the classic haiku structure:
Noble Golden Beer Skillman
Wetmore Lips Aleman
The names in the lower image create:
Texas Manno Wargo Wild
George Izzo Looney
