Chimney vapors. The Watkins stack is no stranger to Winona winters. It’’s been venting high above the elegant neo-classical offices since 1912. The grand entrance bears the somewhat pretentious early corporate name for a liniment manufacturer: J.R. Watkins Medical Company. The Watkins fortune was all from over-the-counter stuff originally sold mostly door to door and mail-order. Medical? Only loosely. Image: Steve Lunde
