I have recently purchased some stamps from a considerate seller based in Denmark. When the envelope was received there was a small label taped to the top right corner with a request that the post office franked the stamps carefully as indicated by the diagrams on the label. Lo and behold, the stamps were carefully franked. The label and franked stamps are shown in the attached image.
With machine cancellations prevalent in the UK I am not sure if this would work in the UK unless the franking was done at the post office counter. Has anyone any experience of similar treatment from elsewhere?
