Thanks to alert reader David for letting us know our original description of this card, from an online source, was wrong.  When someone tells us we’ve made a mistake, we’re going to fix it.  NC16005 appears clearly on the card, but we’re deleting the information we got regarding this particular number or aircraft.  The card itself was issued by American Airlines, with logo, and captions in Spanish and English:  “The speed that only wings can give cuts time and distance to fractions.  It certainly is faster by Flagship.”  Mailed in 1947, with one-cent stamp and Texas postmark.  Grade: 4
