Unknown [Hummingbird with Fountain-pen Beak]

The front side of Arthur Richmond's signal-box mural features a colorful hummingbird whose red beak wraps around to the left side of the box and ends in a fountain-pen tip. The bird's head is dark blue and green, the green carries into the top of the bird's wing that then transitions to dark brown. The bird's back is light brown, and its breast is light purple, light blue, light green, yellow, brown and white. The bird is perched on the branch of what appears to be a birch tree. What the bird is looking at is reflected in its pupil, which is surrounded by a golden-yellow iris. The bird is painted against a white background at the top of the box that transitions to deep orange at the bottom of the box.
