This 1939 commemorative postcard marks the 'cinquantenaire' or 50th birthday of the Eiffel Tower. It is one that any Eiffel Tower collector will want to round our their collection. It represents the first sketch that Gustave Eiffel's engineer, Maurice Koechlin, made of the tower, to illustrate its height compared to other known buildings and sculptures at the time if they were stacked atop one another. This card not only has the special violet-red postage stamp issued in 1939 but it also has a blue ink stamp and verso, it has yet another Paris decorative stamp with an Eiffel design. Note that the postcard was ready to mail with the green 45 centimes postage stamp also added on the back . Would you dare take this card with you on a trip to Paris and mail it from the Eiffel Tower? It is a challenge to find this card in good condition without the light background soiled. There is ink smudging from the commemorative blue stamp but overall, this card has been well preserved and cared for these past 75 years. Size: about 3.5 by 5.5 inches.
