The Book-Cadillac Hotel and the Statler Hilton are two of the most magnificant buildings in Detroit, with it's amazing collection of 1910s and 1920s architecture. DK's excellent book describes in great detail the history of these two landmarks, and updates us on their current sad conditions with brilliant photography. I cannot say enough about the B-C, please check out ... after reading this book, and join the Friends of the Book Cadillac, to assure that the proposed Marriott-led rennovations occur so we can enjoy that landmark for years to come.
