Thanks for Your comments.
You're surely right with the last, but it was pretty hard to find appropiate pictures. So I decided to give espeially the left sides of the fronts just a simple picture, as BMG did on the 70's Masters.
The fronts on the other are not to bad, I think. The "label" is supposed to reflect the sign which is right in front of STAX. studios nowaday.
But You're the professional, any suggestion is welcome. (Maybe on Private Message)
