The bottom cake is three 1 1/2" layers and the top is two 2" layers. All covered in fondant with gumpaste wheels and decorations. The little firearms are toothpicks covered in gumpaste, while the big one in front is a dowel rod drilled through the foam board, with a straw covered in gumpaste over the rod. A very heavy cake! The toy G.I. Joes on the board are 4" high.
