I attended Detroit Public Schools on the east side of Detroit until about 1969. The most exciting thing that happened during the school year, for me, was the week when the teacher brought in the small pamphlet of books that were available to purchase by me and my classmates.

Some of the books I remember purchasing was Encyclopedia Brown, Ivanhoe, and a Tale of Two Cities.
