The image is a photograph of a sign in a museum. The sign is white with black text and is located in front of a blue background. The text on the sign reads "Zielfolgeradar und Leistrahlsender RSA" which translates to "The RSA" in English. Below the text, there is a list of information about the RSA, including the date, time, and location of the event. 

In the background, there are several military vehicles, including a large machine gun and a smaller machine gun. The vehicles appear to be on display, as there are other exhibits visible in the background.
