Hi John and all,
Yep, that would take care of the issue with one issue - pun intended.
Stamps were created as a convenience for postal patrons so they could properly frank a letter and deposit it into the mails without dealing directly with a postal employee long before this Covid-19 era. Very forward thinking those Brits ..
But wait, times and technologies change (advance?) over time. Why do we need them at all today? I get far more eBay
purchases franked with various computer generated labels, etc. that I do with stamps. And, the stamps used are old ones, purchased at less than face value, issued in a bygone era.
