The box fronts have metallic decorations along the five levels of the Auditorium. They are French 7/10-mm thick printed bronze plates nailed to the wood with round-headed bronze nails. The plates were taken away one by one to be restored and then placed again in their original position. Many paint layers were taken off to recover the original bronze and then protected with varnish.
The lights located in each front box have different amount of lamps according to every level. Their origin and restoration process is similar to the auditorium chandelier.
