Do you have this stamp?

If yes, please sell it on eBay. You'll earn almost a MILLION US dollars just for 1 small little old stamp. I used to collect stamps as a kid, and I thought I remember seeing this kind of stamp, but dunno if it is the upside down version. What the heck? Here's the short summary of the news:

In this undated photo provided by Heritage Auction Galleries of Dallas, a rare 24-cent stamp depicting an upside-down airplane is shown. The 1918 stamp depicts a Curtiss JN-4 'Jenny,' a World War I training aircraft that became an airmail plane. A collector from New York has purchased the rare 24-cent stamp depicting the upside-down airplane for $825,000, according to Heritage Auction Galleries.(AP Photo/Heritage Auction Galleries)
