The Rainbow Flag
The Rainbow Flag is the most popular gay symbol. It was created by the artist Gilbert Baker of San Francisco. In fact, the rainbow was used to symbolize sexuality and gender many times. One can meet it represented in African, Greek and American cultures. Later it was used by political parties, as a symbol of freedom. Jesse Jacksons Rainbow Coalition is a glare example of this.

The symbolism was borrowed from other freedom movements such as hippie and black civil rights movement. The popularity of the flag boosted very fast. The purpose to use it yearly at the Parades was achieved. To produce it in a big quantity Baker took it to San Francisco Flag Company. But several colors were commercially not available and were replaced by the other colors. The Rainbow flag became popular all over the world. Now it is easily recognized and widespread. After the 1979 Pride Parade it was recognized not only by common people, but as well by the officials. The existence of such a flag was officially registered by the International Congress of Flag Makers.
