Down Chair (with hidden pictures)

I’ve gotten in the habit of taking pictures of the chairs I see in the street.  This chair sat (for no sitting) on Winslow, off Maltman, in Silver Lake.  Perhaps I should have added legs to the chair.  I drew secret images in the background plants.  Some of the images are more secret than others.  I played with contrast and saturation after I finished the drawing.

Below is the line drawing of the chair, with the first secret message in color.
