My favorite body style of the Skylarks. My Grandfather had a 69 Skylark Custom new in a light green metallic, and I later owned a 69 Special Deluxe coupe in brown metallic with white top.
I had heard that was either Jiarus' or Gary Schmidt's mom. The original art had her in an all white suit but someone (don't remember who) thought it resembled underwear and Jairus added the polka dots
Perry's was not as accurate as it could have been. 3D is the way to go. Your hood looks very close to correct as far as I can see. Some prints had a slight mis interpretation of the character lines from front to back. Yours look right. Have fun.
