MADE IN || WEST GERMANY, no manufacturer on disc.
These are the only two variations that I am aware of.
Back cover "Printed in West Germany" with barcode.
No variations are known.
This exact same disc (no POLYGRAM) was issued in Japan as WEA 38XP-35.
The Japanese catalog number appears only on the sticky obi, as above.
Notes: This disc was not issued in North America, and thus is scarce here.
It is much easier to find in Europe.
