1960 was the first year of the smaller Bazooka box back cards, which were an annual release from Topps through most of the 60's. Colorful and using carefully culled portraits for the most part, these are smaller than the standard-sized Topps cards yet pack quite a visual punch.  This PSA Authentic Roberto Clemente is a real beauty, with vivid color and a neat cut, missing only a dashed line or two on the left edge where it trails off a smidge. This is one of the nicer examples of this card you will encounter.
