MADE IN USA BY PDO
This disc can be found with or without MADE IN USA BY PDO etched around the center hole.

Back cover Printed in U.S.A., no UPC, and new logo.
This back inlay was also used, briefly, for the West German target disc,
and, most commonly, for the non-target US pressings.

Notes: This disc is quite scarce. I have never seen it come up on eBay.
I only know of three copies, and all were found in used record stores.
