Thursday’s ticket gave me half-price entry into the London Transport Museum, so I decided to visit it, if only for the exhibition of art deco posters. Perhaps it’s an exaggeration to say that every other adult had a pushchair, but I certainly felt out of place without a small child in tow. They were pinging about all over the place. It wasn’t the first time I’d been there, so it was familiar. I did linger at the steam locomotive used on the Metropolitan & District underground for over 40 years; it had a condenser to capture the steam but nothing to alleviate the smoke. At first I thought how awful it must have been for passengers . . . and then I thought of the drivers and stokers.

I enjoyed the exhibition of art deco posters from the underground. They implied affordable modern luxury – a visit to Kew Gardens, the zoo or the West End. There were a couple by Sybil Andrews/Cyril Power that I’d seen in Dulwich.

Then, since I was nearby, I headed towards the Courtauld Gallery. I was briefly sidetracked by a youthful band celebrating the anniversary of the founding of RAF air cadets. I looked at the”Courtauld bag” (from Mosul, 1300-30) and was rather taken with Tobias and his fish in the Botticelli painting of the Trinity. There was also a small exhibition: A View of One’s Own: Landscapes by British Women Artists, 1760-1860. I’ve seen a lot of Turner and Constable landscapes recently, and I can’t see that Elizabeth’s Batty’s is markedly inferior.
