There was also a later Canadian pressing -- its front cover has the Mercury Records logo instead of Vertigo, and different distributor details.

Like the UK release (but unlike the French version) the back cover has small cameo images of the original releases of their albums are printed on the back cover, bottom left corner, along with catalog info. This can be differentiated from the UK issue in that it has a Quebec address on the back of the cover.

Subtitled on front cover as "The Best Of..."
