This is a WWII Bermuda Censor Cover from 1941.  It was sent Registered from Prague (at that time the German Protectorate of Bohemia and Moravia) to Seattle, Washington on 10/21/1941.

It has Censor tape 1650 A, but what makes this cover so special is the VERY RARE combination of Bermuda Registration Numbers on the back!  These are the Gray 1707 and the Red 32989, alongside German tape.  This is a truly exceptional cover!

This item is over $100 USD so I will ship it using Priority Mail in the United States, and Registered Mail Overseas at buyer's expense.  This is to ensure that it reaches you in a safe and timely manner, and includes tracking!
