This wall-mounted stamp collection contains some of the most expensive postage marks the world has to offer. The Inverted Jenny, Red Mercury, and Bordeaux Cover are just some of the rare and valuable stamps not included in this reasonably priced collection. However, there are still plenty of desirable letter-enablers within this display, including a rare British stamp from 1982 which depicts a cartoon version of Diana, Princess of Wales giving birth to Prince William.
