24c Curtiss Jenny invert single

These remarkable stamps are some of Benjamin Miller’s special treasures from the late 1800s and early 1900s. The most famous is a copy of the inverted ”Jenny” airmail error of 1918, in which the airplane seems to fly upside-down.

Like the “Jenny,” many of the rarities included here are errors, including other inverts. Some are perforation errors or panes of stamps with one or two of the wrong value. One was printed on the wrong kind of paper.

Others are simply very rare stamps; including the experimental bluish-paper stamps of 1909 and sheets made from the ends of coil stamp rolls.
