According to this story, a letter that had been mailed some 50 years ago with a three-cent stamp (the first class rate at the time) has finally reached its destination.

I have personally done something similar, though it involved sending something very old rather than receiving it.

Many years ago, I was given a collection of old books, magazines, and technical manuals on repairing old tube-type radios and TVs.  (If you have a classic Philco or Motorola TV from the 1950s that you'd love to see work again, I can probably fix it.)

Anyhow, one of these manuals from 1954 (I think) included a postage-paid card for a technical school.  At the time, it was known as National Schools.

Out of curiosity, I mailed it.

And I did get something back.  I received a completely current promotional booklet from National Technical Schools.

It was neat to actually receive something after mailing such an old card.  I only wished for one thing.

I wish I was there to see the look on the face of the employee who received and processed that ancient postcard from a 1950s tech manual.
