This is so cute! I'm moving soon, and am going through all this stuff in the (former) family home, and I found this among some pictures my Grandmother had saved.
Basically, when I was 5 years old, my Grandfather was promising to make me a "Midget racer" (it turned out as a really fine go-kart).
I remember being so happy, I couldn't sleep, and I'd climb into his lap when the poor guy was trying to watch
"Lawrence Welk" on TV....
demanding that he get to work on it!!
So in order to sort of....
facilitate and expedite the process, I apparently made some working drawings, as full of such specifics as a feverish 5-year-old mind could conceive....
