This is the symbol of Sicily. Here is a short description of what the symbol means:

"The word Trinacria means triangle and refers to the shape of the island of Sicily (“Sicilia” in Italian), the largest island in the Mediterranean. The Trinacria symbol is the head of Medusa (a gorgon with a head of snakes), surrounded by three bent running legs, and three stalks of wheat." -Wikipedia

I simply found a picture of this symbol and used blender to extrude it.
