Interesting trifecta of 1909 E92 Croft's/Dockman/Nadja blank back trio. Although the exact sponsor is obviously unknown (E101, E102 and E106 also share poses with the E92 designation), these printing mishaps are extremely rare. Despite a combination of acute creasing and wear, the subjects are still immediately identifiable. Includes: 1.) Casey; 2.) Doyle (Throwing) and 3.) Schlei. Opening Bid $150.
