Somebody else said it was a Moto Guzzi. My dad had one in the 70’s so that’s probably it. Now, the question I will never get answered is, “who is the redhead”. He took that to his grave. All I know for sure is, it’s not me. Mine was that color.
My ggrandmother had a Harley. I did see a picture of her standing beside it when she was old and I was really young but that picture was black & white. We’re still looking for it.
It’s pinky...err... Yellowy Tuscadero!
Was your dad’s name Arthur Funzerelli perhaps?
