Fred Gerrein, whose handsome Sixth avenue residence is shown here, is a well known building contractor, [a stone mason] whose work is to be seen in many of the better class buildings about the city.  His work is not confined to Dayton, however, but extends to different parts of the State where large and fine work is in progress.  The residence here shown he built for his own occupancy, and everything in it is to suit the taste of a man who knows about buildings.
