Kiss Me, I'm Irish! Presented is a 2016 Bryce Harper game-used and signed Washington Nationals cap. The all green St. Patrick's Day equipment was worn by the superstar during a 3/17/16 Spring Training contest. The New Era size 7-1/4 cap is penned #34 in black marker on the interior crown. Displays no hint of prolonged game usage and is entirely absent of any obtrusive wear. The right bill is penned by Harper in black marker ("8-9") and personalized to the original owner by the slugger. Multiple online images show Harper wearing such material. MLB Hologram authenticates game usage and full photo LOA from JSA for autograph.
