I'm a bit of a collector of superhero memorabilia and wanted to pass on some information on the CD. The material was originally released by Golden Records in the mid to late 60's. The Lp would have been released with a comic. In this case, it would have been a special reprint of Avenger #4 (Captain America Joins the Avengers) and followed the comic word for word.Golden Records didn't put much production value into it's children's records. There's no incidental music and the sound effects are a bit harsh on the ears.This CD has a couple of things going for it that the Superman & Batman releases don't. Number 1, It's fairly easy to find reprints of Avengers #4. One can even find scanned pages in various Yahoo groups or on usenet. Number 2, Avengers #4 reintroduced Captain America. Cap was one of the more important characters of comics Golden Age and having audio that faithfully follows the comic is fun. It's geeky, but it's fun.
