If you're a Spidey fan from the 70s, you probably had at least a few of these, eh? Power Records was a division of Peter Pan Records, and their initial product were these book and record sets! The initial Marvel ones, at least, used previously-published comics as the basis for the stories, although some dialogue was re-written and re-lettered. On the Man-Wolf story used above, I believe that Peter Fernandez, the voice of Speed Racer in the original cartoons, did the voice of Spider-Man!
I'm pretty sure the Spidey record shown in the above group was all-original, though!
I have been a Navy journalist, word processor, graphic designer, medical assisting student, cook, and truck driver, and am currently an eBay seller as well as an employee at a big retail store. I have been and always will be into comics, sf, tv, cartoons, monsters, oldies rock, and lots of other stuff.
