1999 US Ryder Cup team autographed golf cap Phil Mickelson Justin Leonard David Duval Mark O'Meara JSA

1999 Ryder Cup beige and tan golf cap or hat autographed in black Sharpie by four members of the winning United States team: Phil Mickelson, Justin Leonard (sunk the winning putt), David Duval and Mark O'Meara. Authenticated by JSA with their Letter of authenticity (there is a Payne Stewart signature on the left that in JSA’s opinion is not authentic but very well could be). Cap has minor to moderate age discoloration on the very back, possibly due to dye leaching from the dark brown leather size strap. ONLY ONE AVAILABLE FOR SALE.
