sunday's Brain Games, Picture D, 51 down. It looks like a gate, but I have ?R?B.
I assume 56 across is ABSTRACT ART, but I could be wrong.
Help gratefully received.

Clue to 56a is'Non-traditional paintings or sculptures' (8,3). I have established ???T?A?Tart, and if 'abstract' is right, the fourth letter of the picture clue 51d would be B.
Thank you for your interest.
