EXTREMELY FINE AND LIKELY UNIQUE. A SPECTACULAR EXAMPLE OF THE PERF 11 5-CENT ROSE ERROR IN A BLOCK OF NINE, USED ON COVER AND TIED BY PERFECTLY STRUCK FANCY CANCELS.
According to the updated census of 5c Red error covers published by Kevin G. Lowther in 2012 in The United States Specialist, only four or five with blocks of nine containing the single error are known. No covers are known with the double error. This is in all likelihood unique with the fancy cancels, and it is the most visually appealing cover with the 5c error we have encountered.
With 2009 PF certificate.
