The image is a photograph of a sign on a purple wall. The sign is rectangular in shape and has the words "CO-LOCATION ENTRANCE" written in bold black letters on a white background. The word "ENTRANCE" is written in a larger font size than the rest of the text. Below the words, there is a smaller text that reads "CO - LOCATION" in a smaller font size. The wall appears to be old and weathered, with peeling paint and chipped paint. There is a small window on the top right corner of the sign.
