The image is a collage of three photographs of a Piranha Subsonic Wind Tunnel Test. 

The first photograph on the top left shows a model of a fighter jet. The jet is blue in color and appears to be made of paper or cardboard. It has a pointed nose and a pointed tail. The model is mounted on a wooden base with a circular base.

In the second photograph, the jet is shown from the side, with its wings spread out and its tail pointing towards the right side of the image. The background is dark, and the jet appears to have a sleek, aerodynamic design. The text on the image reads "Piranha SUBSONIC WINDUNNEL TESTS" and "The Piranhas Model in the Subsonics Wind Tunnel."
