Billy Nattress had an 18 year career in pro ball, all of it spent in the minors. He spent the bulk of that time with the Buffalo, where he was depicted as Bison in T206. The royal blue background is rich and vibrant on this example, which exhibits some corner rounding, perhaps excessively so, and centering that tends to the upper left.  The reverse is a desirable Cycle 350 and the holder is a PSA 2.
