R is for Rainbow is from Sir Peter Blake's 1991 series of alphabet letters. Here Blake replays one of his most enduring images from the 60s: Babe Rainbow.

Blake's wrestlers are a continuation of the vein of escapist entertainment celebrated in his pictures that reflect popular leissure activities.
