This set of 4 ceramic coasters is based on a reproduction of artwork in the private collection of the U.S. Capitol Historical Society featuring some of the most significant documents ever written:  Declaration of Independence, U.S. Constitution, Mayflower Compact and Articles of Confederation against the backdrop of the Capitol dome.  The tiles are approximately 4 x 4 inches and come packaged with a pine-colored wooden display tray.  A cork nonstick back also helps protect your furniture.
