This is a beautiful sheet of 4 stamps, issued in 2012 in Burundi, featuring steam trains. Each stamp features a different model of train, including the Flying Scotsman Express (running between London and Edinburgh), a steam train arriving at the Venezia Santa Lucia station in Venice, the LNER Class A4 Silver Fox (running along the East Coast of England), and the Denver Leadville & Gunnison (which ran through Colorado). The surrounding sheet includes an image of the front of a steam locomotive. The sheet is Post Office fresh, mint never hinged, and F/VF.
