I have two copies of this in my collection. The one pressed at Pioneer Japan is most likely from the first production batch when this title was originally released by Vestron in 1982. It has hand-scratched mint markings and the multicolored disc labels normally seen on Vestron's releases during the early 80's. The one pressed at Pioneer USA is probably from a later production batch when the title was repressed. It has machine-etched mint markings and white disc labels like those used by Vestron on their releases during the later part of the 80's.
