What is wrong with this picture?

I visited the Anglican cathedral in Grahamstown today. And was thrilled to find inside a Keiskamma altar piece...the marriage piece.We were very fortunate, several years ago, to have the major altar piece at Grace Cathedral for a time.

I have below for you three pictures: the altar piece itself, the description I found on the wall, and a picture of where the altar piece SHOULD be...right up front past the screen, at the high altar.

Please join me in praying the altar piece to its place in the Cathedral...out of the corner, right to the place of honor (I actually am not sure it belongs to the Cathedral, but that is beside the point!)
