That's an interesting mix of paper! Any revenue stamps on any of the financial documents?
What are revenue stamps they all have envelopes with stamps
Revenue stamps were used directly on documents to pay a tax associated with a financial transaction. They appear on stock certificates or stock transfer orders, often stapled to a certificate. They are different from the postage stamps used to pay for the transportation of mail.
Yes, it looks like world currency. I'm having a hard time seeing the notes (from the wide angle long shot) & wondering what the question is.... . Completely confused by the other trailing images posted sideways.
