<p>umm the JC:das is standard typing ettiquette. It means that his secretary typed it and that he dictated it. That’s why it’s his initials (JC) and then his secretary’s initials (das).

If it means you got it, then good luck - but it’s standard behavior for “important people” who send letters.</p>
