Harvey Kuenn San Francisco Giants game used bat is a Louisville Slugger model O16 dating from the 1964 labeling period. The ash bat is uncracked and displays outstanding use with seam impressions on the barrel, bat rack paint transfers, and nice wear throughout including some loss of the surface finish. Measures 35.0" and weighs 31.6 ounces, number 7 is written in thick black marker on the knob along with a machine-stamped model number. It is also signed by members of the Giants team including Kuenn, Snider, McCovey, Cepeda, Mays, and more - signatures range in strength as they are signed in ballpoint pen with most around 5-6/10. Kuenn was a threat at the plate, particularly in his early years, as he led the American League in hits four times in a 7-year span. Comes with PSA/DNA LOA grading this vintage masterpiece a perfect GU 10 (note that the letter is for game use only and does not offer an opinion on any of the signatures).
