24c Carmine Rose & Blue, 1918 Air Post, Grounded Plane Variety (C3 var). Original gum, fresh colors, superb centering with wide margins, the plane's wheels shifted well into "Cents" with the blue background lines extending to the bottom of the word

EXTREMELY FINE. A BEAUTIFULLY CENTERED EXAMPLE OF THE RARE 1918 24-CENT FIRST AIR POST ISSUE GROUNDED PLANE VARIETY.

The Grounded Plane stamps are found with a range of vignette shifts, with some wheels just into "Cents" and some shifted to the middle (or rarely through the bottom) of the word. This example, with a pronounced shift, choice centering and sound condition is particularly desirable.

The discovery sheet was owned and broken up by J. Klemann of Nassau Stamp Company. A second sheet was discovered in 1946 and sold in the Thomas A. Matthews sale (H.R. Harmer, Nov. 4, 1964), where it was purchased by Georges A. Medawar, publisher of Sanabria Airmail Catalogue. In Linn's Stamp News of April 21, 1986, specialist Joseph R. Kirker Jr. published his research revealing a third source of this variety.

Ex Price. With 2017 P.F. certificate
