This was the band's debut from 1970. I remember staring at this and many other Sabbath covers right when I first got into them. If everything on the cover were more distinct then it would not have the same effect. I think that the style of the picture helps make the cover. Everything is a little hazy and a little unreal. You can't quite make out the woman's eyes and everything is a little dark. I think it leaves some things to the imagination and it works by implying a little, but not too much.
