I finally found a tiny sketch of the Kooky Spooky design known as Geisha Ghost, who eventually evolved into Grandma Macreak. Since I still had an unbaked batch of the lemon/nightglow Fimo modelling compound, I figured I still had one more custom left in me.
Early "Kooky Spooky" designs (Geisha Ghost: middle of top row).
Created by Patti Peticolas (1968) for Hasbro. Baby Boo (became Baby Spook'em), Shirley Shriek with pendant (evolved into Mama Kaskit), Geisha Ghost with fans (evolved into Grandma Macreak), General Booregard with gun (eventually dropped), Gaston Ghost with foil and shield (became Daddy Cadava, then dropped), Teena Terror. Note: the banjo went to Vincent Van Ghost (who became Rigor Mortimer, and finally Brother Mortimer). Cousin Gilghouly evolved into Daddy Booregard.
Geisha Ghost from the back, and from the top.
A trio of customs: General Gilghouly, Geisha Ghost and Cousin Cadava
The whole gang!
I also made a slideshow to celebrate. View it at PHOTO PEACH!
