The Oakland Athletics finished first in the American League West in 1971, the only year former All Star infielder Jerry Lumpe served on their coaching staff. Lumpe wore this flannel old-style jersey vest as he coached first base for the A's in their first of five consecutive division-winning seasons. The lettered NOB has been restored, but all numbers and the A's logo are original and all trim and buttons are intact. McAuliffe size 44 tag and "71" year tag on the left front tail
