This was an "export" disc, made in Japan specifically for the UK and US markets before domestic plants were operational.

Many collectors prefer the sound mastering on these early Japanese pressings compared to later 1990s or 2000s remasters.

CDP 7 46057 2 1B1 confirms that this is a highly desirable "First Pressing" from 1984, manufactured at the Toshiba-EMI plant in Japan.

Among collectors, this specific "1B1" matrix is one of the earliest production runs ever made for this album on CD, making it significantly more valuable than standard copies.

Black Face design (black paint covering the entire disc surface with silver text), is at the absolute top of the value range.
