Atlanta Exposition 1895 Advertising Cover with Bomar 95-01 Expo Cancel. Rare

Description

Atlanta Exposition November 11,
1895 Advertising Cover with the Bomar 95-01 Exposition Cancellation placed at the Expo Post Office which was housed in a Railway Post Office car in the Transportation Building. This is the only advertising cover known with the exposition postmark. Very Rare.
I have documented 24 postmarks of this type although in the third edition of the Bomar Expositions Postal History book it says that about 40 are known.
The cover had a letter that accompanied the envelope and it is written by a man who was an employee at the Expo. He says that is bitter cold and asked his mother to send him his overcoat ASAP. Additional Interesting contents in the letter.
Shipping and Handling via First Class mail with tracking.
