Loved those 1970's iron-ons; got sent home from HS for wearing my fave "Coors breakfast of Champions" tee shirt.
Local L.A. dJ Wolfman Jack had his late night am radio show on"The Big XERB" iron-on (mail order for $1 buck) another fave
Wolfman had some short memorable scenes in "Hollywood Knights" and "American Graffiti"
Big Daddy Ed Roth "Rat Fink" was a good one as well
