Postcard from Mary to Cash's parents postmarked about six hours prior to the Austin Commencement Address on the evening of June 2, 1941. The postcard reads: "We did see the bones of one shorthorn, but nothing like the fellow in the picture. Thousands on thousands of cows & billions of trees in what we had thought would be desert. Boy has fine speech. Mary" This is one of only two pieces of correspondence known to exist from either Mary or Wilbur written after leaving Charlotte on the fateful trip. The other was a letter from Wilbur to his parents dated June 10, shortly after arriving in Mexico City.
