"Was America Founded as a Christian Nation?" Sighting

My book Was America Founded as a Christian Nation: A Historical Introduction can be used in a variety of ways.  Some use it in the college classroom, others teach it in Sunday School classes, and some just read it for education and/or pleasure.

But if this picture I found today online is correct, it can also serve as one of the building blocks in the creation of a pretty cool "Slinky" tower.  I think I may have found a new market for the book.

See if you can spot the spine in this picture.  Hint:  It is between James Krabill's and David Schenk's Jesus Matters and Willard Swartley's Slavery, Sabbath, War, and Women.  You may also notice that David Swartz's excellent Moral Minority: The Evangelical Left in an Age of Conservatism sits atop the pile.
