Thanks for the picture, Mark. If you get a chance to stop by Holy Redeemer in Webster Groves, they have cool Advent decorations.
I don't recall seeing an altar with a painting of the crucifixion above it before...is that common around St. Louis?
The Old Cathedral is the only local church I can think of that has a painting of the Crucifixion. Here are better photos: http://www.romeofthewest.com/2007/09/photos-of-basilica-of-saint-louis-king.html
