The Christmas exhibit this year is a stained glass style Nativity poster with gorgorous blue and gold tones – set off with big old-fashioned-like colored bulbs (although they are actually the new LED style lights now)! 
The artist of the original painting is Terry Bain (1967- ).  Bain resides in Spokane WA and is a husband, father, artist and author. 
The exhibit case is located on the lower level near the chapel of the Province Center.  The Nativity poster will be up through the Feast of the Epiphany which is celebrated on Sunday, January 8, 2012.  Hope you get a chance to see it!
