Doors are the ultimate metaphorical treasure trove, signifying entrances / exits, beginnings / endings, hope / despair….   Sometimes, however, a door is just a door.  While there are doors of all shapes, sizes, and pretensions, the doors in this series are decidedly of the functional variety, service doors in two-and-three-family flats in my San Francisco neighborhood.   Walking around my neighborhood, I began to notice the symmetries and asymmetries, the color combinations, the decorative twists, the moods of these random pairs, and I wanted to give them their moment of recognition.
