Good old Charlie Brown?
No, but close.
The above frame is
Charles M. Schulz's
"Harold."
Harold appeared in
Young Pillars, a biweekly
single-panel cartoon created by Schulz for a
teen magazine called
Youth.
Young Pillars ran from 1956 to 1965.
Below is a sample.

Hundreds more of these teen oriented cartoons
are collected in
Schulz's Youth.
