The image is a postage stamp from the Republic of Congo, issued in 1999. The stamp features a photograph of a blue and purple electric train on a railway track. The train is a C-C Electrique (France) model, which is a type of electric locomotive used by the French Railways in the early 20th century. The locomotive is painted in a combination of blue, purple, and green colors, with a white stripe running along the side. It has two large windows on the front and a small door on the side, and a large antenna on top. The background of the stamp is a landscape of trees and mountains, with the sky above. The text on the stamp reads "Republique du Congo Postes 1999" and "400F".
