Tennis court signs emphasize positivity with "No Complaining" and "Encourage".
Medium shot of a black semitransparent cloth sign on the chain link fence of a tennis court with white text "NO COMPLAINING" in a serif font. Through the fence you can see a tennis court (with red out of bounds and green in bounds), then another fence and two more black signs saying "NO QUIT" and "ENCOURAGE" in the same style, then another court through that.
