Well, I have to admit that I only have one actual issue of "Drag Cartoons"... HOWEVER, I have been collecting "CARtoons" magazine since 1969, which was originally started by Mr. Miller and Carl Kohler back in the fall of '59. Pete started Drag Cartoons when he had a falling out with Kohler. Or maybe it was someone else, as it has been a long time since I spoke with Pete (He passed away back in '01 or so).
I have nearly 80% of all "CARtoons" published, as well as 100% of all "Hot Rod Cartoons", 100% of all "CycleToons" and 94% of all "SurfToons" magazines. This encompasses nearly all the Petersen Publishing cartoon periodicals. (There was one other that came out in 1967, "SkiToons" which is the rarest of all being, published only once, a copy of which I also happen to be in possession of.)
I talked to Pete Miller about a year before he passed hoping to get him to illustrate and contribute a page of cartoons to Model Cars Magazine. I received the permission from Gregg Hutchings, editor. And we agreed on a page rate, but Pete was a little vague on commitment, so the deal never materialized.
I always loved his cartoons... except when they got political (I suspect he hated the NHRA) and miss the humor to this day... thanks for the reminder.
