A confluence of shapes created the suggestion of a person seated.

The sign either read "CAT Rental The Store," or "CAT The Rental Store." The back of the building had a roll-up door and a human door both painted over.

The art was unsigned. The only sign was on the door and gave a California warning that the building's interior might contain cancer causing materials.

The closest thing to a signature was a swirl of blue spray paint near to the driveway surface.

The back of the CAT Rental building was painted in a random pattern in a manner that resembled a mural.

Part of the painted wall resembled a blue hamburger or a mine shaft drilled down through blue shale.

One bit of the mural looked like metal folded over. But on closer inspection, the folded metal was merely an effect of the paint.
