Marek worked at the Polish section of BBC Radio for decades as an art critic.  That occupation, along with the books he wrote on the subject and actually being an artist himself, meant he was, unsurprisingly, quite opinionated about it all.

I don't know if The Times ever published the letter he quotes. I hope so, as then there'd be a written record of my dad's use of English, rather than just my translation. Throughout his memoirs, he quotes several letters he wrote to The Times and The Observer. He was a bit of a busybody by the looks of things.
