That happened to me too! I mean I received a card where the stamp part looked like this too. I wonder why, maybe the sticker is not a real stamp
Maybe this is the reason... By the way: you're still wearing your Christmas hat!
Haha! I just don't bother to change it. But I have just changed into a new one! :D
Maybe it is something to do with machine sorting? How annoying! I found this blog post which explains the universal mail stampshttp://commonwealthstampsopinion.blogspot.co.uk/2012/06/universal-mail-united-kingdom-stamps.html
