True, I certainly knew that the Internet exists in its current form relatively recently.
Of course, I received letters with addresses before 1991, well, the maximum was 1970.
But what would the letter be dated
1899 (!) A year, I confess, I saw only today! Spam is of course, not a letter, but the fact itself made me laugh and surprised.

By the way, an idea appeared - who received letters dated by earlier years? Screenshots "in the studio", as they say;) Oh, i.e. in the
comments on the original topic ;)
