Sharp's Drug Store was a longtime occupant of the ground floor.  It was the tallest commercial building in Manatee County from completion until 1986 when the 12-story Bradenton Financial Center surpassed it.  Designed in the Commercial or Chicago School style of architecture with Classical Revival touches, it features the three tiers typical of the Commercial style: an ornate main floor exterior, plain middle story exteriors and a not quite as plain top floor crowned with a cornice.  Today the building is owned by the law firm which occupies most of its space.  The ground floor exterior has been restored to its original appearance.  It is included in a walking tour of downtown Bradenton and is included in the city's master list of historic buildings.
