Interesting uncut panel featuring four blank-backed cards depicting members of the 1960 Tacoma Giants the AAA team of the San Francisco Giants. The panel features Bob Perry Matty Alou Tom Haller and a young Juan Marichal. The future Hall of Famer would go 11-5 for the Giants striking out 121 in 139 innings before being called up to the Big Club where he'd finish the 1960 season with a 6-2 record and a 2.66 ERA. The panel which measures approximately 5 7/8" x 10" has the player names handwritten underneath their likeness. The year "1960" has been written in what appears to be black marker on the Alou card and the top of the panel does feature a few pinholes and one larger hole along with some creasing at the upper-ridge edge. National Bank of Washington sets are very scarce today; their regional distribution limited just to Tacoma and its suburbs. Graded "Authentic" by Beckett with the set name unmentioned the sheet itself is much more yellow and toned than cards from the issue are typically found today. That along with the blank backs (the finished cards included a National Bank of Washington logo on the reverse) lend credence to this being a proof sheet of some sort. A very rare likely one-of-a-kind uncut sheet featuring a pre-rookie card of Hall of Famer Juan Marichal.
