These are much easier to read and the label is slightly smaller, 55mm x 60mm instead of 59mm x 65mm. The 'postmark' graphic reminding us that it is a single use only label has gone and the space used for an extended address reference, now including the start of the street name and there is a new code running vertically in the bottom right corner.
Below are some examples of the various labels I have received in the older format.
The shades do seem to vary quite a lot, from an almost colourless grey through grey-green to a distinctly brown flavour. They may not have the charm of Machins but are quite interesting none the less. And they don't require me to examine my bank balance every month!
