No creases & back is clean but has a red mark that has been erased. I just broke up a 1970 Topps set that was over 90% NrMt, NM-MT & MINT & I am currently listing the cards. Many of them are PSA worthy, so take a close look & see if they meet your needs. Many thanks for looking at my auction item! (The number in parenthesis at the end of the title is the date of my listing).
