This collection of Z-Silk Baseball cachet cards are in excellent condition with bold and vibrant colors that demonstrate the technique beautifully. The signatures themselves range from 8 to 9 out of 10 and vary in medium from blue sharpie, to blue and black ball point ink. Some of the HOFers included in the album are Brooks Robinson, Billy Williams, Juan Marichal, Bobby Doerr, Rick Ferrell, George Kell, Lou Brock, Stan Musial, Frank Robinson, and Wille Mays. There are also several group cachets, 5 commemorating the 1969 Mets, such as one featuring Jack DiLaurio, Rod Gaspar, Wayne Garrett and Donn Clendenon signed by all 4 players as just one example. There are many other baseball greats included in this collecion of Z-silk cachets and there is no doubt that this collection is a prime example of the medium.
