The obverse of the coin features a portrait of Gustave Eiffel posing in front of an arch of the tower that bears his name. The portrait has been drawn in such a way that the features of the face, the hair and the clothes of the man are made of rivets, as if Gustave Eiffel was one with the metal structures that he imagined throughout his life. The reverse of the coin features representations of some of the architect's major works. At its centre, the Eiffel Tower seen from above divides the design into several zones. In the space to the left, the Statue of Liberty reveals its skeleton. Above the top of the tower, one can see the Garabit viaduct. On the right is the plan of the aeroplane designed by Gustave Eiffel, the LE. Finally, below the tower is the Maria Pia de Porto bridge, which straddles the face value.
