I have a collection of original American comic strip art, and this is a panel from my 1955 Pogo strip (with some politics which are still relevant when Pogo was running for president.
I was heavily influenced by Pogo when I was learning cartooning. In my high school comic strips, I drew a lot of Walt Kelly trees, I loved them. And I remember following the stories in my local paper when I was a kid. Walt Kelly was certainly a master.
