The image is a photograph of a signboard for the Central Line platform in Westbound. The signboard is white with black text and is framed in a red wooden frame. The text on the signboard reads "Central Line Platform Westbound" in bold letters at the top. Below the text, there is a list of stations and their names. 

The stations are listed in a grid-like format, with each station represented by a different color. The stations are:

- Liverpool Street, St. Paul's, St Paul's Bank, St George's Lane, London Court Road, London Circus, Marble Arch, Notting Hill Gate, Wood Lane, Ealing Broadway, Greenford, West Ruislip, and Denham.

There are also two arrows pointing in opposite directions, indicating the direction of the station. The arrows are pointing towards the stations, one on the left side of the image and the other on the right side. The background of the poster is white, and the text is black.
