Letter without contents sent to Hindrich Flemingh, Arboga, with a manuscript notation on front "den 26 Junij (1)636 Uthi Arboga ankomit och Påsten på stunden tillbaka med swar afskickadt", which means that the letter had arived in Arboga on June 26th 1636 and that the answer had been returned with the Post. The word Post in the note might indicate that this letter, as well as the answer, was conveyed by the general post. If that is the case, this could be the earliest known surviving letter sent with the General Post.
