This is a very well-traveled Mauritius cover, sent in 1894 to Paris.  However, it was redirected to Lucerne, and then returned to Paris.  It has Swiss and French Postage Dues!

Ex Ibbotson.

This item is over $100 USD so I will be shipping it using Priority Mail in the states, and Registered Mail overseas.  This is to ensure that it reaches you in a safe and timely manner, and includes tracking!
