The image is a diagram of a tile-end and tile-nail. It is a black and white illustration on a beige background. The diagram is divided into three sections. 

The first section on the left shows a triangular shape with a pointed top and a curved bottom. The top section has a small hole in the center, which appears to be a drain or a drain pipe. The bottom section has an oval-shaped hole with a small opening at the bottom.

On the right side of the diagram, there is a line drawing of a pipe with a curved end and a small pipe at the top. The pipe is connected to a horizontal line that runs along the length of the pipe. Below the pipe, there are Chinese characters written in black ink that translate to "Diagram of Tile-End and Tile-Nail."

At the bottom left corner of the image, there has a circular logo with a stylized design. The text on the image is written in both Chinese and English.
