I am in a post office program called Informed Delivery. Every morning they send me an email with scans of everything I am going to receive that day. They take pictures of everything that moves through the system. I cannot believe they have not tracked down every package that looks even remotely like these.
On another thread I questioned why (as one of the photos showed), one of the packages had no cancellation marks.
Find that very strange if it came through the USPS.
