I woulda guessed ’83, but this is ahead of it’s time. And there’s more info on the cover art than damn near every other book on here combined:

“The cover of this book is one of ten views of a kinetic painting, ‘Pyramid’, by Oliver Bevan. The painting is made of transparent materials which only assume colours when illuminated by polarized light. When the plane of polarization is rotated slowly (which happens mechanically in a box designed to display the painting) the colours pass through a recurring cycle of change. Ten points of that cycle have been recorded to provide covers for the third set of ten volumes.”

That means I gotta find 9 more books…
