This is an advertising slick for the Prince album "Rave UN2 the Joy Fantastic." This was at the time when Prince was having it out with Warner Brothers and was using a glyph for his name instead of Prince. I remember that when he started using the glyph it created trouble for all print and other media because no one had that glyph in their computers. Warners had to send out discs with the glyph on it to all media outlets so they could report the story. What a mess for Warners. But apparently all is forgiven because Prince is back on Warners again.
