A half plate negative. A port side view, taken from ahead of the beam, of an unidentified spritsail barge under sail in the Thames or Medway during a Thames or Medway Barge Match. She is on the starboard tack, has a white canvas jib and her white race number 5 flag is attached to her foretopmast stay. Her owner's bob is just out of the picture. The image is not sharp.
