The front cover is a curious place to place a bookseller label but save for that fact I wouldn't have grabbed this detached front cover of Political and Constitutional History of the United States by Ralston Hayes and Oie Worth Stephenson (1918) from a pile of papers at an estate sale. George Wahr of Ann Arbor was the publisher. The Slater Book Shop was located on State Street in Ann Arbor, Michigan. It is the building with the third awning from the left.
