Kahn's Meats added three more teams to their 1960 mix and continued their perennial inclusion of Roberto Clemente, as this collector-grade PSA 4 shows. Miniscule print runs were still the norm, as was insertion of the cards into hot dog packages, which made things greasy sometimes. This example show some evidence of this but it doesn't affect the image of Clemente. The back is similar to this, with only a small area of identifiable staining present.
