Box on wall

Went to Lord's today to watch Middlesex v Surrey in the Royal London Cup. Spotted this covering set into the wall. I used my IPhone as cameras are not allowed in the members' areas at Lords.

Sat in the Long Room in the Pavilion for a while (first time since we bought our membership). Amused when after half an hour's play a steward came into the Long Room and boomed 'Gentleman may remove their jackets'. Middlesex lost.
