Steel 3.5 x 8.5 inches. Large engraved printing plate with a block of 20 North Dakota 1 cent cigarette tax stamps. Vignette of a prairie dog at center. Plate no. 85791. This unique plate is part of an exciting offering from the Continental Collection of American Bank Note Company Stamp Plates unlike virtually anything we have ever offered. The term unique is absolutely accurate here as these plates represent the actual dies used to create the finished products and in many cases trial designs along the way to a finished stamp mostly for late 19th and early 20th Century issues.
