This is a home cap used by the "Taiheiyo Club Lions," the predecessor of the current Saitama Seibu Lions, from 1973 to 1975. There is no tag on the inside, so the details of this cap are unknown. Also, there are some stains. We would appreciate it if you could purchase this item with the understanding that it is a used item. #TaiheiyoClubLions #Lions #ProfessionalBaseball
