The recent issue of The Titanic Commutator (Titanic Historical Society, Vol 33, Number 186) reports of a recent attempt to sell a fake Titanic envelope. The envelope was put up for sale online at the UK eBay site with an asking price of £750. The letter appeared to have sent from RMS Titanic to a Mrs J Woods, Altringham, Manchester. But according to Paul Louden-Brown it is a very clever fake.
The stamp used on the envelope appears at first glance to look legitimate but a closer examination reveals it is likely a stamp issued between 1934 and 1936. The King George stamp of 1912 looks similar to 1934-1936 but there are important differences. There was no solid color behind the King’s head in 1912 but rather lines. Also the 1934-1936 stamp turns out to be a rare stamp used for only two years. Brown also notes the paper used is typical of the waxed paper used after World War I rather than what was in use in 1912. Also the handwriting style Brown notes is more typical of the years after World War I. Other things such as the postmark being too large and the lettering too thin point to it being a fake. And it is not difficult to fake franking marks by using a heavy object.
The lesson here is simple: be very careful in buying Titanic memorabilia. Buy only from reputable sources that have authenticated the items as being genuine. And never ever buy such memorabilia sight unseen over the Internet.
