27th October 2022 | administrator London Zoo has a pillar box painted in zebra stripes for visitors to use to make donations. Chessington Zoo has one in tiger stripes. Many former Post Office/Royal Mail letter boxes have found their way into private hands, or are now preserved in museums, or displayed by other organisations. If they were once official postal boxes the LBSG records them all. The LBSG Directory, available to Members, records every genuine box, in use, in private hands, or abroad.
