A saturated linen-era view of the iconic Mayo Clinic tower rising above downtown Rochester, Minnesota — sent airmail in January 1964 by a patient (or companion) navigating the world-renowned medical campus. The writer, signing off as "Mary," reassures her friend that the clinic and surrounding conference center are beautiful and that doctors expect a positive outcome soon. The warm ochre brick of the Plummer Building's ornate Renaissance Revival tower dominates the composition, an American flag flying proudly from its copper-green pyramidal cap, vintage automobiles dotting the streets below in cheerful period color.
