Translation / modern text
This is an actual letter, not merely a cover, but it is badly damaged. The address to a Most Honorable Lord Benefactor and references to the Sejm and officeholders can be recognized. The damage prevents identification of the precise request, sender, and date. The date 30 August 1634 appears on the inventory card as catalog information.

Reading notes
Page 1 is an inventory card, not the letter. It gives a catalog start date read as 30 August 1634. Handwritten date notes on page 2 do not yield a certain, consistent reading. The record date is left blank; authorship and signature remain uncertain.
