VERY FINE APPEARANCE. THIS IS THE ONLY SURVIVING PANE OF 100 OF CONFEDERATE STATES "NUMBER ONE". UNQUESTIONABLY ONE OF THE MOST IMPORTANT ITEMS IN ALL OF UNITED STATES AND CONFEDERATE PHILATELY.
The 1929 edition of August Dietz's The Postal Service of The Confederate States of America (pp. 102-103) contains individual photographs of the left and right panes of the full sheet of 200 that at one time belonged to Sen. Ernest Ackerman. The Ackerman sheet was divided into two panes of 100, and the right pane was further divided into two blocks of 50 (5 vertical x 10 horizontal), each block representing the group of 50 subjects on the lithographic transfer stone that was repeated four times on the printing stone of 200. There is no record of another pane of 100 or larger multiple of the 1861 5c Green from Stones A-B, 1 or 2.
Bertram Poole used the Ackerman sheet as the basis for identifying characteristics of each of the 50 positions on the lithographic transfer stone (published in the Philatelic Gazette, October 1915). Contained in a manuscript supplementing Poole's descriptions is the following statement: "Poole's descriptions were taken from a full sheet of four panes ["pane" as used here refers to the transfer blocks of 50], (the only one known) which was then the property of Mr. Klemann, and which Mr. Ackerman purchased, and in whose collection it now is. Hence I call stamps from this stone 'ACKERMANS.'" The previous owners, the Hall family, acquired the pane of 100 as lot 211 in the Robert Laurence May 23, 1935, sale of Confederate material from the George Walcott collection (it realized $600 in the sale).
