Large metallic purple ink signature, "Prince,” on a light purple 7.75 x 6.5 sheet. In fine condition. From the collection of Prince's assistant Stachia Fiedler, who notes that this was signed on Prince's 27th birthday, June 7, 1985, at his 'Masquerade Ball' party at the Prom Center in St. Paul. Accompanied by a full letter of authenticity from REAL and a letter of provenance from Fiedler. An ideal example of the 'Purple Rain' creator's autograph.
