Super Graphisme

I didn’t imagine it. There was a trend for painting massive graphic murals (I’m talking several stories high) on old brick buildings around the late 70s/early 80s. About the time when bright, primary colours came into fashion (for Melbournians think Knox City Shopping Centre circa 1980). I recently found evidence in a 1971 edition of French house magazine La Maison de Marie Claire, as these scans from said magazine show. Any chance of a revival, do you think? Seems like a cheap way to do up a crappy old building.
