About 6 people will get the title of this one..
Anyway, this 1977 drawing was swiped from a BATMAN FAMILY (loved that book) comic. Maybe one of the Curt Swan drawn stories.
An early attempt to understand female anatomy, realizing it ain't just a male body with some bumps added...
Looks like I lost interest when the time came to draw the thug's lower body...And my signature...And the background details...I thought then a HINT of background was enough....Hey, you were lucky to get THAT!
Check out the size of that noggin on Batgirl! Wow!
