“The post-modern pineapple,” writes Alice Ralph, identifying September’s I Spy photo, “tops the building for Liberty Title at 111 North Main.” Adds Siri Gottlieb: “It may have been installed as a nod to home ownership. The pineapple came to be a symbol of hospitality in Colonial times.”

Indeed, according to a 1991 Observer article, the pineapple and other architectural elements were added by Liberty Title owners Tom and Michele Richardson as a playful riposte to the construction of the drab, eleven-story One North Main next door. The pineapple in particular, Michele said, was intended as “a warm, welcoming symbol to people coming into town.” Entrant Herbert Winful finds it so. He writes, “[I]n the deep freeze of winter, the sight of tropical fruit sprouting on top of a downtown Ann Arbor building always makes me smile.”
