Front cover of the booklet
Rear tray insert, "Printed in West Germany" with no UPC.
This back inlay is a grayish-green color. The more common black letter discs come
with back inlays that are more decidedly green in color.
Notes: This disc appears to be harder to find than the black letter disc, at this time.
I say "appears" because this variation was just recently noticed, and not enough
copies have surfaced yet to make a definite determination. At this point, it doesn't
appear to be "rare" but there seems to be fewer copies available than the black letter
variation. That could change over time.
