The Guide Book is published in the interest of the business men of Ann Arbor, Michigan; the visitors that come to the city to attend the many different amusements that Ann Arbor has to offer during the winter season, such as the Choral Union Concert Series and the Extra Concert Series which are held in Hill Auditorium-one of the finest buildings of its kind in the United States.
