Ah yes, Spring! When a young man's fancy turns to... SQUINTING!
Here are some caricatures of various people squinting.
All of the reference for these came from a 1980 yearbook
I bought years ago at one of my favorite used book stores,
the World Famous BOOK ALCOVE.
I'm not sure if this foxy lady knows what squinting is,
or even how to squint,
but she was just too good to pass up, so here ya go.
Oh yeah, and here are all my sloppy sketches, too.
