4c Green & Black on Violet Paper, Center Inverted (RB4ac). Lightly cancelled, deep rich colors and detailed impressions, reperfed at right, trivial corner perf crease at bottom left not mentioned on accompanying certificate

VERY FINE APPEARANCE. ONE OF ONLY 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 the five stamps other than this, one is defective, one has a piece missing, one has a repaired corner, one has a tear and abrasions, and one has a light horizontal crease. The example offered here is one of the finest.

With 1992 P.S.E. certificate
