In November 1963, golf heavies and showbiz elite joined together at the Canyon Club in Palm Springs to pay tribute to Frank Sinatra in a five-day swingfest in the desert. It was the one-time-only, PGA-sanctioned, Frank Sinatra Invitational, followed by a black-tie gala in the ballroom of the Palm Springs Riviera Hotel. Presented as souvenirs and given to the 150 VIP guests in attendance was a custom-crafted, Toney Penna-designed, MacGregor IMG-5, heel-shafted putter. Each of these copper-plated gems had the Sinatra signature and caricature likeness forged into the head. None were ever sold, only given out as gifts to the celebrity and amateur swells in attendance. Today they are regarded among the most treasured items in collectible golf. According to putter expert and noted collector Bobby Grace, less than two-dozen examples have surfaced over the years. Grace reports having sold one in Japan for $21,000. This example does show use and would bring a grade of very good to excellent. The putter has been authenticated by Mr. Grace and and will come with his Letter of Authenticity.
