The Abraham Lincoln Book Tower! You can find it across the street from Ford’s theatre in Washington D.C., as a part of the Lincoln exhibit attached to the house where he died.
This tower is 34 feet high and took only 2 weeks to create! My sister and I were debating whether they had to add a new book to it every time another Lincoln biography was published, but apparently they created this tower in 2010 and haven’t gone back to add anything to it.
When I die, I would like this done to the books I own.
