As Horacio pointed out in the comments, Batman makes a cameo on this 1968 Design Magazine Cover. Such a specific pop culture reference seems a bit out of place among it’s vaguely evocative surroundings (the Union Jack excluded).  As the title suggests, this all must be in reference to Carnaby Street which was sort of a fashion / cultural center to the Mod movement in 1960s England.  Perhaps it had lost it’s hip status by the time this issue was published and the cover depicts the death knell of the movement.  At any rate, a very nice illustration worthy of framing. Right after you clone-stamp out the byline at the bottom, that is.
