A continued search of an accurate setting and uniform combination reveal what SHOULD be present for any Addie Joss Day image.
Compare the baseman's uniform to that of the subject RPPC. Also the stadium features, from what is visible in this example photo (courtesy of REA), we can see that the stadium layout, structure and paint scheme match that of League Park (image from Leland's). This Addie Joss Day photo catches the end of the 3rd baseline grandstands, in the background. Also note, that there are no stands along the flat outfield wall.
