A fine Italianate brick store and key building in the heart of the commercial district, this is one of the few buildings of this type and vintage that were not lost to fire or random replacement. The first of three druggists to occupy the building was G. H. Corwin. A rear addition housed the first telephone exchange in Greenport in 1906 and in the 1920s, a speakeasy was situated on the second-floor rear.
