Looking towards house left at the stage from the house right balcony.  The curtains on the side are there to hide the damage done by the removal of the boxes. Not an uncommon situation in theaters of this type and age. The boxes often got in the way of wide screen presentations.

 House right from stage right. again in the Riverside.

 The Dome over the Riverside auditorium. Probably not the original chandelier.

 Detail from the ceiling of the Riverside Theatre. It appears to be Christopher Columbus asking for financing for his voyage west. The mural above the proscenium appears to be Columbus discovering America (maybe New York - how "urbocentric").

 Soundboard above the proscenium detail.  Looks to me like he is discovering something.
