This artwork was done in black ink on a special stationary. It depicts the moon right on top and the fact that its signed Night Stalker as well explains that its a victim that had the hads cut with no legs that died and is in a sort transition.
The wings can be explained by this transition in becoming some sort of spirit or angel right after she had died.
This was done in the year 2000 and is signed in full Richard Ramirez Night Stalker.
