One of the most difficult variations of all the "E" cards, presented is a vibrant 1909-1910 E97 Briggs Lozenge Dennis Sullivan (Boston) variation. Produced by said company in Boston, this SGC 40 specimen reveals only minor staining on the front and reverse. The olive-green action caption is unobstructed and presents well. With only a handful of examples having been graded, this gem is a true feat for the caramel aficionado.
