The image is a photograph of a wooden sign in a rural area. The sign is rectangular in shape and has a white background with black text. The text reads "Australia's First Public Railway" in bold letters at the top. Below the text, there is an illustration of a train with a red and white color scheme. The train appears to be a steam locomotive, with a black and white checkered pattern on the side.

The sign is mounted on a wooden post with two screws on either side. The post is located in a grassy area with trees and bushes in the background. The sky is blue and the overall mood of the image is peaceful and serene.
