The Carl Lundgren (Cubs)....Bill Dahlen (Brooklyn)....and, Kid Elberfeld (Washington portrait) are the toughest....besides the "Big 6".
Certain T206's such as these three are scarcer than most, simply because they were printed with less T-brand backs. Shown here
are the only 3 backs that Lundgren is found with. Similarly, Elberfeld exists with only three T-brand backs. Dahlen has only 5 backs.
While most T206's were printed with anywhere from 6 to 24 backs....making them much more available.
Furthermore, as plentiful as the ever popular Red Cobb is, it is extremely rare with a SOVEREIGN 460 back. Only 4 of these are known.
