The image is a photograph of a sign hanging on a wall. The sign is rectangular in shape and has a white background with black text. The text reads "Appendectomy Project" in bold letters at the top. Below the text, there are four squares arranged in a grid-like pattern. The squares are of different sizes and colors, with the largest square in the center and the smallest squares on the left and right sides. In the center of the grid, there is a black symbol of a radioactive symbol, which appears to be a circle with a cross in the middle. The symbol is surrounded by a thin black line. The image is taken from a low angle, looking up at the sign.
