Am I going mental or is this an oddity?

Was playing a stack off me Detroit shelves Saturday night when I noticed this.

Emanuel Lasky, Welfare cheese / crazy  on Thelma is Vinyl but has a ZTSC stamp.

Anyone noticed or own any others.

Yes, there's also an ARP stamp in the runout, so it was mastered at Columbia and pressed at ARP. A few others like Eddie Hill and both Joe Matthews also have ZTSC numbers, but were plated at Nashville Matrix before being pressed at ARP, so the numbers are etched instead of stamped.

Thanks Nick

I noticed that other Thelma/Ge Ge records were ZTSC but this was the first stamped vinyl copy I had noticed.
