The Last Recording of Mankind?

So hopefully this message landed onto a few doorsteps. It could have been the last thing that anyone had ever printed. Civilisation could have vanquished overnight and this might have been what was left in a red pillar box waiting to be distributed by the postman. Granted, there would have been other more interesting materials out there such as unpaid bills and magazine subscriptions depicting our current way of life. But this was printed on an island where perhaps some sort of civilisation would have been able to have taken shelter from the disaster. It doesn’t state what the event was but hopefully people at the time would have been tuned into what’s occurred. There’s also some reassurance that the postage has been paid, though by whom and for what service it doesn’t say. At least it attempts to be informative and bring good vibes despite what the event was.
