Recent sales have confirmed the desirability of T206's with tougher backs and this El Principe De Gales of Bunk Congalton is a freshly-graded beauty hiding in a PSA 4 holder.  A vertical blue print line running up the right side obverse can be seen but does nothing to detract from the brilliant green background and wonderfully registered central image. The all important EPDG reverse is stunning and bright.
