Walter Johnson is a Type-1, Gehrig & Cobb are T2's.You can instantly determine types by the print direction on back.Type-1's were printed with grey or white backs.Type-2's are always white backs. Grading companies (ie. PSA & SGC) even get confused on T1 vs. T2 so always check the print direction on back to be certain. Some Type-2 cards have the same saying and player as Type-1, only the print direction on back was changed. Other T2's may have a different player or same player with a different saying such as Cobb's (compared to Jeff's Cobb above).
