The signature is in hand written letters and must be Starr, as the two P's are two small r's, which gives the name Starr. The writing is identical to Leonard Starr's signed story "Mad Dog of Manhattan" in Crime & Punishment #10. Starr signed his work with capital letters too, but not here. The artwork has many similarities with early Starr work like "Vampire Prowl" in AITU #3, on some grinning faces and folds in clothings.
Art credits verified by Leonard Starr in Alter Ego #110 (June 2012).
