Four days ago, this message appeared on twitter - from Royal Mail News (http://twitter.com/royalmailnews):
Howzat! We're celebrating the bicentenary of @HomeOfCricket with this special postmark!
It’ll appear on mail delivered to the NW8 postcode area, home of Lord’s
However I didn't notice the message, and was only alerted to the new postmark by one of our readers who sent this:
Is Windy Miller giving somebody out? Well maybe Royal Mail News, because our correspondent is in Hertfordshire, not St John's Wood, so the usage is not quite as restricted as they suggest. Or it maybe something to do with the fact that the first match MCC played at Lord's was against Hertfordshire CCC (see BBC News).
Either way, this is a postmark that Cricket collectors will be looking for, so if you live in St John's Wood or Hertfordshire and have one to spare, please let me know. Many thanks.
UPDATE: We have had reports of another example being received in Romford, Essex, and one from Gatwick MC to .... Pretoria South Africa!
