I made this a couple of years ago for hubby's 30th birthday. He's a huge Grateful Dead fan. Bottom was a 9 x 13, top a 9 inch round. I printed a copy of the steal your face symbol, cut out the pieces and laid them on the cake, and then used a toothpick to trace the symbol onto the cake (this was before I knew about the pin prick method). All buttercream.
