10" base with bricks on two sides and then the batman and superman logos on either side of that. 8" middle tier surrounded by royal icing buildings. 6" trimmed top layer with AA (boys name or initials) made by my husband out of gumpaste. I had a different idea for the look of the letters but he came up with that. I stuck skewers in them and poked them into the cake. I had fun doing this, but the bricks took FOREVER!
