I found quite a few interesting articles about letter writing, the postal service, and on-line forms of communication in the process of putting together the mail show currently at Mindport. All the articles are available to be read here at MP, but I recognize that all that reading usually takes more time than most visitors have during a trip to the museum. Here are the links, so you can read as you will!
