12 blotting papers, 12 figures! Here is a very rare series of the 50's, monuments located in Paris.
On exercise-book sleeves, we notice three other monuments in bold: the Trocadéro, the column of July (Bastille) and the Luxor obelisk with its two fountains, which are still never seen to this day. It would total 15 references ,which is quite unlikely. The Eiffel Tower is the rarest part, as well as the Assembly and the stock exchange with their flag.
