I was surprised that Royal Mail didn't choose to mark the out-of-world experience of Tim Peake in reaching the International Space Station with a slogan postmark. More worthy than the non-British winners of a book prize, I would have thought, but they obviously had more pressing things in mind.
Having exhorted everybody to 'Post Early' last month (and weren't there a lot of people making their annual visit to the Post Offices to post their 'maybe large' cards?) they are now reminding us of the last posting dates for 1st and 2nd class mail, as in this example from Norwich Mail Centre dated 14 December.
Actually, thinking back to previous years, this is probably not the last slogan as we will probably have one from Monday 21st suggesting the use of Special Delivery for those last-minute must-get-there-by-Thursday gifts.
