But the argument which ensued among some of the visitors and which became serious when three factions appeared was concerned with the relative merits of the picture in the various possible positions.

"Doorway" shows two doors opening into a short hallway. The doors have no distinguishing latches and the only feature which might differentiate top from bottom is the beamed ceiling. Even this factor does not seriously affect the picture when it is hung upside down.

One faction dubbed themselves the "Upsidedownians" and firmly maintained that the true quality of Sheeler's art was only expressed when the painting was upside down. Another faction--the "Rightsideupsians"--put up a determined stand in favor of the artist, and decreed that the picture was not a picture unless it was in its correct position.

Still another group, made up of visitors who had twisted themselves into contortionists and gazed at the picture from a horizontal position, deplored the oversight of the directors, who had failed to try the sideways possibilities. These men called themselves "Sidewaysians" and their spokesman said, "I think it should be hung sideways. It looks just like a bulkhead door opening.
