Red brick rising ten stories above the palms of St. Petersburg's First Avenue North, the Princess Martha Hotel stands as a proud sentinel of Florida's Jazz Age boom — early automobiles angle-parked along the curb, storefronts bustle at street level, and the warm Florida sunset bleeds orange behind the skyline in this richly colored linen card mailed in the summer of 1935. Opened in 1926 at the height of the Florida land boom, the Princess Martha was one of St. Petersburg's premier addresses, later serving as federal offices and eventually converted to affordable housing — making period images like this one genuinely evocative of a vanished glamour. The sender, Gladys, wrote to Mr. and Mrs. W. S. in Port Huron, Michigan, sharing a breezy travel update: "Hello! We have had a wonderful trip. I think we are going thru to Montgomery from Tuesday, but will get us in Hannibal on Fri. I am going back to Daytona Fri. Mills will write you when we get back to Mo."
