Without that final criterion, we might get a fascinating snail-mail-loop:
like an email loop, only a billion times slower. *:^)

The pink cards were stapled or taped to the back
of the registered letter. They were removed upon
delivery, stamped , and mailed back to sender.

Later the pink cards had a detachable gummed tab
along one end of the card. The gummed tab was used
to stick the card to the registered mail.

Upon delivery, the card was removed (there were perfs
between the card and the tab to do this) while the tab
was left on the registered cover.

Well you learn something every day. I have been collecting
stamps for more years than I care to count (well over 50 anyway)
and I was not aware of the prevalence, never mind the
existence, of these AR cards!
