Can I ask what your source is for your upload, File:M61BoltonKenning.jpg?
I ask because the photo on the postcard is under copyright, putting us on dodgy legal ground. You can get around this by saying you're only posting it to show people what the postcard looks like (which is what I always say!), but to be able to do this the exact file you uploaded has to have been created yourself (or uploaded with the permission of the person who created it) - otherwise you're distributing someone else's work, landing us in an even deeper legal hole.
I'm just making sure because, as the site owner, it's me who ends up losing sleep over these things!
