The image is a photograph of a sign that reads "Celebrating the Hill: Harrow's Secret Heart". The sign is displayed on a white wall with a purple border. The text is written in black font and is divided into three sections. 

The first section on the left side of the sign has a photo of a group of people gathered around a red telephone booth. The photo shows a snowy landscape with trees and mountains in the background. The second section has a list of information about the hill, including the location, the number of people, and the date and time of the event. The third section has an image of a red building with a white roof and a blue sky.

At the bottom of the page, there is a purple banner with the Harrow logo and the words "Harrow's secret heart" written in white font.
