Nice pair of signed pin flags from the 101st US Open Golf Championship in 2001 at Southern Hills Country Club in Tulsa, Oklahoma. Both are of identical make, measuring 22.5x13.75", yellow, with Open/Southern Hills logo across the middle, white strip on left side with three metal grommets. 1) Single-signed beauty in 7/10 black Sharpie by the legendary Tiger Woods. 2) Over 25 signatures from other participants in that field, including Phil Mickelson, Duffy Waldorf, Matt Grogel, and Jim McGovern, averaging 7-8/10 in various ink, mostly black Sharpie. Each flag is accompanied by an individual PSA/DNA LOA.
