Very cool story (here) about an artist — Harriett Russell — who decided to test just how dedicated the Royal Mail really was to getting her posts delivered.
[She concealed] the addresses of 130 letters to herself in a series of increasingly complex puzzles and ciphers. Among the disguises she employed were dot-to-dot drawings, anagrams and cartoons…. Amazingly, only 10 failed to complete their journey back to her.
I loved to hear just how seriously the postmen and women took their job. One particularly clever challenge — the address as a series of crossword clues – came back “Solved by the Glasgow Mail Centre.”
Apparently this correspondence of sorts will be featured in a new book, Envelopes: A Puzzling Journey Through the Royal Mail.
