Is there a web site for the tire swing cartoon done by Jules Pfieffer ?

I think this might be the original : http://sethglassman.com/Cartoon.jpg

And here is a cleaned up version : tree swing pictures - tire swing, tire swing, rope swing cartoon pictures

Is this right?

All I could find was this - - - - http://sethglassman.com/Cartoon.jpg.

And this one - Tire Swing Cartoon
