The image is a photograph of a display board with three different types of objects displayed on it. The board is divided into three sections. 

The first section on the top left shows a circular object, which appears to be a coin or a token. The object is orange in color and has a curved shape. It is placed on a white background.

Next to it, there is an illustration of a wooden structure with a triangular base and a triangular top. The structure is made of wood and has four legs. The legs are arranged in a diagonal line, with the top leg being slightly higher than the bottom leg. The bottom leg is slightly lower than the middle leg and is attached to the base of the structure with two screws. The text on the board reads "3-D Reconstruction of the Docks with the Lumber Locks" and "The Grommets with the Shadow Scale".

On the right side of the board, there are two illustrations of a black and white model of a submarine. The submarine is shown in a side view, with its body and fins clearly visible. The background is a light beige color.
