Offered is an unusual blank-backed example of Southern Leaguer Dom Mullaney (Jacksonville) from the legendary T206 series. Blank backs are very scarce, and according to T206Resource.com, they currently rank as the tenth most difficult back variety (out of thirty-nine). This is a very presentable example with bold colors, flawless registration, and evenly rounded corners. Centered to the left with moderate creasing and mainly clean reverse. Encapsulated as "Authentic" by SGC because all blank backs are hand-cut. This is a very unusual (and in our experience extremely rare) printing anomaly that is likely to be of great interest to collectors of all the various nuances of the legendary T206 set.  Reserve $300.
