BTW, I discovered that the US are issuing un-perfed staps, like the 29
cents stamp on this cover.

I have never understood why most self-adhesive stamps come with
"perforations" (other than because of some innate conservatism within the
business). Surely they do not make the stamp more easily separable from its
surround, if that has not already been removed during the production
process.

Self-adhesive freezer and address labels do not come with perforations.
