4c Green & Black on Violet Paper, Center Inverted (RB4ac). Deep rich color and sharp proof-like impression, neat August 30, 1872 manuscript cancellation, light horizontal crease at top is barely visible without fluid

VERY FINE APPEARANCE. THIS IS WITHOUT QUESTION THE FINEST OF THE SIX RECORDED EXAMPLES OF THE 4-CENT PROPRIETARY INVERT. AN OUTSTANDING RARITY.

In his privately published census, Larry Lyons records six examples of the 4c Proprietary invert on violet paper (none is known on green paper). Of these six, one is defective, one has a piece missing, one has a repaired corner, one has a tear and abrasions, and one is reperforated at right. The stamp offered here, with a light horizontal crease barely visible without the aid of detection fluid, is the closest to sound of the six recorded copies.

Ex Joyce and Zoellner. With 1989 P.F. certificate
