More than 300 fans flocked to the Paisley Park Studios of the rock star formerly known as Prince in suburban Minneapolis on Saturday to snap up his leftovers. Many of the souvenirs at the garage sale went for a song. Among the booty: keyboards, tambourines featuring the Artist symbol and equipment cases with “PRN Productions” stenciled on them. The singer also got rid of a Victorian dining room set, TV sets, mahogany leather chairs, stereo speakers and two neon signs reading “Coin Castle” and “All Nude.” Nowhere in sight, however, was The Artist himself.
