1990 Upper Deck Mark McGwire #656 raw single card featuring the Oakland Athletics slugger mid-swing. The card showcases McGwire during his early career years with the A's, before his record-breaking 70-home-run season in 1998. This is an ungraded raw single in near mint condition. The front displays crisp imagery and color, with the classic Upper Deck design of the era. The back includes biographical and statistical information typical of 1990 Upper Deck releases. A solid addition for McGwire collectors and vintage baseball card enthusiasts.
