The World’s Fair
This is a first day cover for the #3 cent U.S. Postage Stamp honoring Puerto Rico and showing the Governor’s Mansion “La Forteleza”, postmarked October 31, 1939. It appears to have originally been sent from Mineral Wells TX on July 15, 1939, a little over 4 months before it was franked at the World’s Fair in New York. There is a letter inside, but it’s a personal message from the recipient’s father, who taught Physics at Science Hill High School.
