The image is a photograph of a display board with information about the function and structure of a ship. The board is divided into three sections. 

The first section on the left side of the board has a black and white photograph of the ship, which appears to be a battleship. The photograph is accompanied by text in Japanese that explains the different types of ships and their functions. The text also mentions that the ship is a minesweeper and that it is a specialized hull structure for minesweepers.

In the middle section, there is an image of a large ship with a crane on top of it. The ship is shown in the center of the image, with the text "Hahajima" above it. On the right side, there are two smaller images of the same ship, one showing the ship and the other showing the structure. The background of the display board is white, and the text is written in black.
