Vietnam's poster

This is the poster that I see on Luong Dinh Cua street. It is used to commemorate 62 years since Uncle Ho proclaimed the declaration of independence on September 2,1945. The poster is pretty impressive as it uses red and yellow, the flag's colors of Vietnam, as the main primary colors. The first thing I notice on this board is its wide red part. Thought it's simple, I can see the expectation of a developed country by the images of the pigeon flying to the city, where there are only modern buildings and skyscrapers.
