This mural of bicycles was painted on the side wall of 645 Brannan Street in San Francisco. Parked cars obscured the bottom of the mural.

A closer shot of the top of the mural. You can just make out chain sprockets in the upper right, and handle bars in the lower center.

The artist's signature was in the upper right of the mural, just above a bicycle tire.

The lower left of the mural, below the handle bars, was the front fork of the bicycle, and the front tire.

A head peeked over a parked car in the lower right corner of the mural.

A closer look at the design in the lower right of the mural, obtained by leaning around a parked car.
