Very nice mint, unused set of 6 collectible Inverted Jenny stamps. Catalogue value is $24.

Nearly a century ago, the purchase of a single pane of U.S. stamps turned the collecting world upside down. The "Jenny Invert" became the world's most famous stamp, and the 100 examples were eagerly sought after by prominent collectors. Billionaire investor Bill Gross was one of them.

In 2005, Gross paid $2.97 million to buy the unique Jenny Invert Plate-Number Block. He then exchanged the block of four stamps for the 1868 1¢ Z Grill owned by Don Sundman, president of Mystic Stamp Company, in a one-for-one trade that made international headlines.

To commemorate the gallery's opening in 2013, the U.S. Postal Service issued a souvenir sheet of six $2 Jenny Inverts. This sheet was printed using plates created from the original 1918 dies. Now collectors can see the legendary Jenny Inverts on display and add a reprint of the famous "Upside-Down Airplane" stamps to their own collection.

The selvage artwork around the stamps pictures the National Postal Museum, aviation pioneer Reuben H. Fleet, a map of the first scheduled Air Mail route, and a compass rose.
