I take it to be the postcard that is returned to a sender whenever something is mailed via certified mail, return receipt requested. The signed receipt means that the document(s) to which it was attached has been received and signed for by the recipient. In this case, the divorce papers were received and signed for by BHO Sr. The post office then returned to the lawyer the receipt (both sides shown) with BHO Sr.’s signature, proving that he was served with the papers, because he signed the receipt (unless that’s not his signature).

HERE ARE IMAGES OF BOTH ITEMS:

Perhaps David can tell us what these images suggest?

I think it’s either side of the same postcard. I’ve sent items certified mail, return receipt requested. The post office attached a small green postcard to the item being mailed. When it was delivered, the postal employee had the recipient, the addressee, sign the postcard, ensuring that the person got the package. Then the signed postcard was returned to me.

This is how one typically ensures that something important was not only mailed, but received by the intended person. It’s wise to do whenever you want to make sure that someone has received something, so that later on he can’t claim that he didn’t get it or that it was lost in the mail.
