A mural in celebration of "Bulgaria U.S.A." was painted on the walls of two handball courts. The lack of a fence and a stack of wood indicate that these handball courts were no longer used.

The back wall of the handball courts were painted in the colors of the Bulgarian flag.

An eagle flew over a knight on a horse. Both were colored as if they were made of gold.

A closer shot of the eagle. Notice the green highlights under its wings. Possibly a green reflected from the green stripe of the flag.

An elaborate sign was painted on the lower right corner of the mural, just behind the golden lion's butt.
