The image is a photograph of a plaque on display in a museum. The plaque is rectangular in shape and has a white background with black text. The text on the plaque reads "Hartnett 1948 Prototype" in bold letters. Below the text, there is a brief description of the prototype, which states that the prototype was designed by Jean Gregoire. 

The plaque is mounted on a black surface and is placed in front of a blue wall with a metal rack in the background. The rack appears to be part of a larger display case or exhibit. The background is slightly blurred, but it seems to be a part of the museum's interior.
