25-31 W. Oak - Both Dr. Edwin Greene and his son-in-law Jake Wey were pharmacists, and in 1906, they opened side-by-side drugstores. Later, Jake Wey's establishment became a Rexall Drugstore and then was purchased by Dr. Louis Koch. Koch swapped storefronts with C. E. Adams who had opened a mens wear shop in the Rosin Arcade. Adams' shop became Mercer's as commemorated in the stained glass sign in the transom window.
