We organised a sort of school trip on Tuesday. Sadly, there was no coach hired for the day and we didn’t ask people to bring packed lunches with them. The plan was simple: anyone was welcome and all you had to do was get yourself to the Design Museum in Kensington for the opening at 10.00 and we would purchase the required tickets to see the Enzo Mari exhibition. It has been a choppy weather week in London, including a thunderbolts and lightning storm, but Tuesday morning was all spring promise and sunshine. I took the Underground and walked through Holland Park, a world of elegant houses and groomed pooches.We weren’t a huge crew – perhaps a dozen – but our team included interns and editors. Everyone was free to wander on their own and meet back at the office but seemed to prefer walking around together, reading about the life of the maverick Italian designer who railed against consumerism while making some very covetable products, from toys and furniture to books and art. But there were some incidental things that also stuck with me.Mari worked with the Japanese furniture company Hida Sangyo and there was a wonderful photo of all its employees. It was shot in the factory and staged with rising tiers of people so that everyone could be seen, even if some of the younger men were holding on to the roof supports to get in the shot. Anyway, it got me thinking that an annual company photograph would be a rather splendid thing – and an easy way of recalling who was here when. Perhaps a pre-Christmas party moment? Just as school trips are so evocative, it’s funny how many homes you go to and see a panoramic photograph of all the pupils in someone’s old school displayed in the loo.
