This image is from a parking barrier constructed of a heavy yellow plank bolted to two large posts. This bolt was well into its rusty phase, with rust stains spilling down below it. The plank itself was faded with dings and chips and peeling paint.
This was the raw material for the abstract study in texture and color below. As with many images on the web, some of the color and textural detail from the full-size original has been lost.
