I don't think there's anything wrong with a cartoonist merchandising his work in any legal way. I never thought less of Peanuts because Snoopy appeared on every single commercial product ever invented except for condoms, diarrhea medicine and lima beans. I therefore have no snide remarks about the fact that it will soon be possible to purchase Hi-Top sneakers decorated with images on Robert Crumb's Mr. Natural. But some who remember the underground comics movement of the sixties will take it as a reminder that things have changed since then.
