3407 ROMANIA - Puzzle map of Romania - series of postcards

3407 The summary of the series
"100 years since the Great Union of Romania"

At the initiative of Mihnea Răducu, between 1st December 2017 and 1st December 2018, so in the year in which the Romanians celebrated the centenary of the Great Union, took place every month a meeting of the Romanian postcrossers, and at each meeting has been edited a postcard to recall this exceptional event for the Romanians. 
  

The all 12 postcards of the series
"100 years since the Great Union of Romania"

Moreover, each postcard contains a fragment from the outline of the borders of Romania and a letter, such that if you put together all the 12, you make on one side the map of Romania and on the other side the word "Postcrossing". Finally, Mihnea edited a postcard to solve this puzzle (3407). The 12 postcards can be seen here:

About the stamps

The stamps are part of the series Centenary of Traian Vuia, issued on March 18, 2006, on the occasion of the centenary since the historic flight in the airplane Vuia I in the field of Montesson (France) pioneer of the global aviation, Traian Vuia. Traian Vuia (1872-1950) was a Romanian inventor and aviation pioneer who designed, built and tested the first tractor monoplane. He was the first to demonstrate that a flying machine could rise into the air by running on wheels on an ordinary road. He is credited with a powered hop of 11 m made on March 18, 1906, and he later claimed a powered hop of 24 m. Though unsuccessful in sustained flight, Vuia's invention influenced Louis Blériot in designing monoplanes. Later, Vuia also designed helicopters.
