Interesting story in the New York Times:
In 1945, some seven years after he had been regularly illustrating
Superman adventures written by his partner, Jerry Siegel, Shuster
encountered a young man who looked exactly like the Superman character
as he imagined him. He asked the man, named Stanley Weiss, if he could
draw him, resulting in some sketches that have gone largely unseen for
nearly 70 years, as well as some insights into the origins of this
long-lived American champion.
