Comic Book Cats, number 161: Tomorrow Stories #3
Comic Book Cats, number 161: Tomorrow Stories #3, drawn & lettered by Kevin Nowlan and written by Alan Moore, published by America’s Best Comics / DC Comics in December 1999.
Cats always land on their feet, and buttered toast always falls to the floor butter-side down, so kid genius Jack B. Quick decides to see what happens when you spread butter on the back of a cat. Oh, that poor, poor kitty!
A few years ago this was a gag in a commercial, but Alan Moore & Kevin Nowlan got there first!
Kevin Nowlan has worked in comic books since 1983, both doing full artwork and providing inks / finishes over other pencilers, as well as providing numerous covers. He has a very distinctive, slick, polished style that is very well-regarded.
