Hi all! Hopefully this is the right place to post this.
I am looking for a book that showed hundreds of pieces of mail in which the addresses were encrypted or coded somehow and the lady who sent them documented how many actually arrived at the destination (most of them!).
I felt like I had read about this on the Postcrossing blog or somewhere else in Postcrossing, but I could not find it anywhere. I searched the internet but could not find it anywhere. So, I turn to you, dear Postcrossers (:
AH ha! I believe I found it. Thanks for the help, everyone! For anyone interested, it was called Envelopes: A Puzzling Journey Through the Royal Mail by Harriet Russell.
