This is what I believe the two half-slits looked like for the 1966 Topps series 7 print run. I have placed the Raymond card above the Tigers team but don't have enough info for the Skowron, Cueller, checklist, as well as a few others (e.g., Queen). We know that 532 and 552 are next to each other, and that 517 (W. Sox variation) is at the end of a row. We also know that 576 is above a Mgr or Rookie card.
