Richter Scale

One of my favourite pictures at Frieze, by Gerhard Richter
Oh, and the geezer in front is the redoubtable Sir Terence O'Ryan.
We also took in the impressive Reza Aramesh show at One Marylebone and a lot of artbollox at ambika p3, a 14,000sq.ft. underground hangar hidden away in the heart of London.
