Just the thought if this album cover would turn my stomach for years after first seeing it. The fact that it's not blood but some kind of weird jelly really, really upset me.

A related little story:
So I was about 10yo in 1983, and had a brother two years older. This was probably the starting point in the "Satanic Panic" era in American culture. My family was only kind of religious (Xmas and Easter Catholics), but we still had to go to CCD (Catechism class or 'CCD', basically Sunday School).
Well my brother comes home from CCD one night and tells me that they had a special program that night. An "expert" came in and put on a presentation called "Pandora's Box". It was all about Satanic and Occult themes in rock n' roll. He would show how if you turned the Dio logo upside-down (OF COURSE) it would spell out DEVIL. He played records backwards and basically scared every 12 year old in the room.
I couldn't wait until my class got to see the same presentation because it sounded AWESOME.
