I really thought this would have been answered already. I found nothing in the archives and searching the boards froze my IE twice.
So anyway, in Back to the Future III, Marty gets a letter from 1885. The guy delivering it was like “We all had a bet whether you’d be here. Guess I lost!” In Quantum Leap, Sam mails a letter from the 60s to the future so they could open the imaging chamber for him.
Would that really be possible. If I wrote a letter with such instructions as “Do not deliver until 1999” in 1960, would they just throw it away? Would it sit on a shelf somewhere forever with all the Santa letters and unreadable letters or something?
If I mailed a letter right now to some address that does not exist, and say “Do not deliver until 2025”. And then I buy some property in 2020, make a street to my house and number the house the same as the address on that letter - could I expect to receive that old letter?
Any USPS or UPS etc. people here who could tell me what you’d do with such a letter. And/or what people 100 years would have done with such a letter.
