Something new on the Horizon front? This label was on a package that came today. It is curious in two ways: first it has the 'Single use only' addition, looking a bit like an old postmark might have done, and, secondly, the background seems to have a deliberate fade out running top right to bottom left.
This is identical, other than the source and fee detail, to another that came in on another parcel. So what looked like a poorly printed 'gold' label is as it is intended to be.
My guess is that the pale background will make the printed stuff easier to read, should anyone actually need to, and the 'postmark' might be intended to discourage people from reapplying these to new parcels. That had never occurred to me!
