New Post and Go Postmark from City of London.

Thanks to Robert for sending this picture of the postmark that was used to cancel his Faststamps from the Camden Christmas Post Shop.

Update: I have been told that this was taken, not by Robert, to Eastcheap City of London PO. The device used is normally used for Post and Go certificates of posting.


Are there any other Post and Go postmarks in use to cancel stamps?
