Here are some charming original art pieces for covers in Charlton's Beetle Bailey and Sarge Snorkel comics. The artwork is signed "Mort Walker" but most likely it's a ghost. Frank Johnson is a likely candidate.
I love the expression on Sarge's face above and how it's mirrored by his pampered pooch.
I've had students like this.
And I'd imagine this is an early design for smart bombs.
