I still have the Freak Brothers comics as well, and have often wondered what (if anything) they might be worth, especially since they contain some work by R. Crumb as well as Gilbert Shelton and Bill Griffith. I’m way past “Doper Humor” at this point, but I have to admit, some of that stuff was pretty creative.
My favorite one was when they were camping and warned Fat Freddy not to feed the bears.Freddy told them not to worry,he was feeding them some acid.They [Phineas and Freewheelin Franklin]took off running leaving Freddy getting bearhugged by one of the tripping bears.
