Previously, I stated that there was a PDO inscription on this disc variation. Apparently, I was wrong.
Although there SHOULD be such a disc, I have no evidence of its existence. Sorry about that!
To be clear (I hope), I am aware of four disc variations of this target CD.

Front cover of the booklet.

Rear tray insert "Printed in West Germany" without barcode.
Found with the top two disc variations.

Rear tray insert, "Manufactured in Germany. Record Service GmbH, Alsdorf" no barcode.
Found with MADE IN WEST | | GERMANY disc variation, released in Europe. Note the catalog numbers on the spines.

Notes: This disc is not common, but shouldn't be too hard to find.
Thanks to Uli in Germany for some of the scans.
