Secondary pressing with different run-off groove notations:
Side A: The Robot
Side B: The Robot
There are three UK 12" sleeves: The original first edition has a die-cut sleeve with cut-outs and a silver inner sleeve.
Later editions and re-pressings have die-cut sleeves or plain black sleeves with just the colour coding. The original inner sleeves are either thick glossy black carton or thin black paper.
The coloured strip is not random - it spells out the Catalog#, band name and both song titles.
The back cover of "Power, Corruption and Lies" has the same colour coding, done with the alphabet (a decoder ring).
