The image is a photograph of a signboard hanging on a metal rack in a train station. The signboard is rectangular in shape and has a white background with black text. The text reads "Northern Line Platforms 2 & 3 Northbound" in bold letters at the top. Below the text, there are three lines of text that read "Brent", "Hendon Central", "Colindale", "Burnt Oak", "Watling", "Edgware", "Brockley Hill", "Elstree South", and "Bushey Heath". The lines are arranged in a grid-like pattern and are pointing in different directions. There is also a red circle in the center of the signboard.
