Aviation meet postal card
A major aviation meet was held on Kinloch Field, St. Louis, Missouri, October 4-7, 1911. During this meet, Walter Brookins (1889-1953) flew official US airmail each day. He flew the mail from the field to Fairgrounds Park, a distance of about twelve miles, on October 4, but on subsequent days, he flew mail only from one end of Kinloch Field to the other.
This card was one of those flown to Fairgrounds Park on October 4. It bears the inscription "Aerial Mail," which was required by the St. Louis postmaster on all mail to be flown. It is a one-cent government postal card, one-cent being the proper rate because special airmail rates had not yet been set. Cards franked with two-cents postage do exist since the pre-meet publicity indicated that all mail to be flown must be franked with two-cents postage. As this card verifies, that was clearly not the case.
