18-card sheet. From the scarce rare-number 4th series, the sheet contains cards numbered 290 - 347. It features four different Yankees from this difficult series: Kubek rookie, Carey, J. Collins, and D. Johnson. Key card of the sheet is Brooklyn Dodger great, Sand Koufax #302. Five cards are touched by a crease in the sheet (Koufax is clean with a gorgeous image). Overall the sheet technically grades VG-EX because of light creasing but presents as EX-MT. If you’re a serious Sandy Koufax collector, I wouldn’t let this slip by. Tremendous eye appeal.
