Although it was not mentioned in his book "The Black Raider",[1] it seems that Weyher was a non-trivial painter; in a feature article[2] author Keith Gordon[3] tells that on the voyage of the Orion Weyher did about 30 paintings on subjects connected with the ship's activities. The one painting illustrated seems to have had narrative merit and to have represented the topographic background recognisably.
