Fanta and Screwball Squirrel (I think). Lester, 1981, for "The 5000 Fans of Dr. T" Issue Zero

I recognize Lester's signature from many other (on-model) drawings of Fanta in C/FO publications from the 80's, but don't know anything else about him.
He's always credited as just "Lester" even in print.
