The marker for Sp4 John Graff is the first pentacle gravestone in the form of a marble niche marker at the Columbarium at Arlington National Cemetery in Virginia. It is located in Columbarium 8.

This pentacle marker was dedicated in a private cemetery on Wednesday, August 23, 2007 by Rev. Selena Fox of Circle Sanctuary.

Fox assisted Graff's next of kin, his son, and his former wife, Boudica, a Wiccan priestess, in obtaining this pentacle niche marker.
