My dad has always had an obsession with the Cardinals. When they tore down Busch stadium, he bought two seats. Unfortunately, they were meant to mount on a vertical surface. I fabricated custom mounts and a concrete colored base after I decided on the most comfortable angle for sitting. These seats even have cup holders now where the adjacent seats mounted.
The bottle cap was meant to hang on the wall. Three child-size bats were beveled at the end to provide a stable leg angle. I built a triangular steel frame for the bats to screw into under the table. Eyebolts and turnbuckles gave the legs additional stability.
