EXTREMELY FINE. A REMARKABLY WELL-CENTERED EXAMPLE OF THIS DESIRABLE ONE-CENT SAGE ISSUE ON PRUSSIAN BLUE. EASILY ONE OF THE FINEST USED EXAMPLES IN EXISTENCE.
Collectors of France and the Sage Issue are well aware of the challenge to acquire this stamp both sound and well-centered. This is, by far, the finest example in either unused or used condition that we have offered since keeping computerized records.
Signed A. Brun. With 2020 Roumet certificate (noting "bon centrage"). Scott $4,350.00 (specifically noting "values...for examples with the perfs touching the design"). Yvert €6,000
