I just watched a very cute television show out of England called Terry Prachett's Going Postal. I loved the playful and inventive way they came up with stamps, but was a little lost on some of the fantasy details like the golems. I definitely recommend it to all postal enthusiasts out there!
A little fantasy, a lot of letters, and some fun! Check your Netflix to order the DVD sent to you. And for those of you that prefer reading to watching, know this was originally a book.
