you are absolutely correct. i'm a big enough nerd that i went back and finally found old copies of eerie and creepy and looked at thier back issue ads. it's not there. so, you win 100%. i am wrong.
so, i guess that means that frazetta really should not be taken seriously because he did a cover FOR molly hatchet, right? he was that big of a turd. too bad. i thought i was defending his integrity. ah, well...
well then, maybe it creepy's sister magazine eerie. either way, it was an old re-use of a frazetta image.
frazetta did a lot spot gag-cartoons in early men's magazines. during this period he was an inker for al capp on his l'il abner strip (those frazetta chicks are all actually variations of daisy may). he began doing the famous work on creepy and eeire for warren magazines (also publishers of famous monsters - which actually began life as a me's magazine called "after hours". james warren fancied himself as a sort of lowbrow hugh hefner.) he started doing the images for those magazines because he was fast and good cheap and worked down the hall. he hung around with a crowd of body builders and sports junkies and car geeks that included ron haydock who wrote and designed for ackerman and warren on fm.
anyway, without those early issues of creepy, frazetta would never started his eventual carrer, as far as i can see. creepy and eerie were his launching pad. that's where he did virtually all of his most famous and earliest work.
after that he worked on blazing combat and then he landed the conan and tarzan stuff. the rest is lowbrow kulture history.
well, actually frazetta did that image used on the molly haychett cover for a magazine called "creepy" where it was a cover image.
molly hatchet simply licensed the use of that image like 10 or fifteen years later to use on their record. so, frazetta didn't really do a cover for molly hatchet, he just took their money and giggled.
