One of the factors that complicate researching the Star of David symbol is that the Hexagram is the name of a few different things:
A. The six-pointed star (Star of David)
B. The Unicursal hexagram (drawn unicursally)
C. The name of each of the 64 yin-yang diagrams in the Chinese Book of Changes (I Ching)
D. The name of a large silver coin issued by 7th century Byzantine Emperors (Heraclius, Constans II, and Constantine IV)

The stars that we see here are NOT Stars of David but three out of the four red hexagrams that adorn the Chicago Flag. These stars stand for:
Solomon's Seal on Ethiopian Crown along with a cross (at the top). In the background we see the Lion of Judah. All these were symbols of the late Haile Selassie I (1892-1975).
