I wrote earlier about this work, when I came across a recording of it by Barenboim and the Berlin Philharmonic. Somehow I cannot find this recording online, it must have been quite unimpressive. I find the artwork on the cover quite fascinating. It reminds me a bit of this one, I am wondering if it might have been the same photographer.
So… luckily I have both of these in the house. I checked, yes, it turned out to be the same photographer: Cor van Tol. Cor was creating covers for Philips during the Seventies and Eighties, and they share this recognisable (apparently) style. I own another one: the Holberg Suite. Other than his collection on Discogs I cannot find more about him.
