EXTREMELY FINE. A BEAUTIFUL AND RARE VERTICAL PAIR OF THE 29-CENT NEW YORK STOCK EXCHANGE ERROR, CONTAINING ONE WITH AN INVERTED CENTER AND ONE WITH THE CENTER OMITTED.
Two panes in total were discovered. This block comes from the first to be discovered, which was auctioned in 2002. Each pane consists of 40 stamps, and of these 28 were with the centers inverted and 12 were with the centers completely omitted.
