The Mighty Dr. Illusion
This 45" is such an anomaly; it's the only Shazam! one they ever did, and(as far as I know) they never did a Book and Record version of it, nor did it ever get included in any collection of other DC hero stories. Plus, I've never even seen it listed as part of the collection on any of the other Power Records.
The cover looks like Dick Giordano channeling C.C.Beck!
