natural s.e. at right, 16mm sealed tear and scuff at top, thin
spotFINE APPEARING EXAMPLE OF THE RARE 24-CENT INVERTED JENNY. AN EXCELLENT OPPORTUNITY TO ACQUIRE AN EXAMPLE OF AMERICA'S MOST FAMOUS STAMP.
According to Jenny! by George Amick (Amos Press, 1986), the original sheet of 100 inverted "Jenny" stamps was purchased by William T. Robey on May 14, 1918, one day after the stamp was placed on sale. Robey bought the sheet at the New York Avenue Post Office window in Washington, D.C. Soon after, the sheet was sold to Col. Edward H. R. Green through Eugene Klein, a Philadelphia stamp dealer. Green paid $20,000 for the sheet, then instructed Klein to divide it into singles and blocks, and to sell all but a few key position blocks.
The stamp offered here was offered in one of the auctions of the Green Collection (Sale XV on March 27, 1944) where it was described as not having any gum. Presumably, mishandling by Colonel Green was the reason for this. It was next offered as part of the Max Simon Collection in 1966.
