Fun With French Curves

Clearly, this one's ready for the Whitney Biennial of a a half-century or so ago! I'm not 100% sure of the tool employed; the line is too thick to be Bic Banana, but it's not a chisel-point, which rules out Magic Markers or El Markos. I can at least tell you that it's drawn on typing paper. I suspect this is actually a pen test, rather than a regression to a three- or four-year-old skill level; the rest of this pad of paper can be pretty conclusively slotted into the 1974-76 range (lots of Star Trek, no Star Wars), and there are other more coherent pieces involving this same French curve/protractor thingy.
