I don't know why but I occasionally feel the need to doodle from old 1960s comic book covers, especially by Neal Adams. Nothing detailed. Really just the big shapes.
Was watching an old documentary on the Kennedy clan and all the old b&w photos got me to pick up a pencil and start doodling - mostly searching for the bigs shapes.
Close studies of line technique from a late 1960s comic book cover done by Neal Adams. Also, some line weight analysis from Stan Drakes "Hearts of Juliet Jones" daily strip from the late 1950s.
