The picture shows both sides of this 1901 Buffalo Exposition Lowney's Exhibit Building Cancelled Ticket. At least I believe it is a ticket. Maybe it is a souvenir item. It is cancelled with a numbered punch. Each side pictures a different World's Fair Lowney Exhibit Building. The sides are marked as follows:
THE LOWNEY BUILDING AT THE CHICAGO WORLD'S FAIR 1893
THE LOWNEY BUILDING AT THE BUFFALO EXPOSITION 1901
The sheet or ticket measures 4" x 6-1/4". It is in excellent condition with one fold crease.
