National flag of Mexico. It is made of synthetic bunting, the hoist is a cotton and linen blend and the flag is machine sewn with the arms embroidered onto it. A rope and two aluminium clips are attached. Design: three vertical stripes, green, white and red. On the central stripe an eagle with a rattlesnake in its mouth, standing on a prickly pear growing from a rock surrounded by water. Below is a wreath of oak and laurel leaves. This coat of arms was adopted in 1823 and continued in use with periodic modifications. Although this flag was made in the 1950s or early 1960s, the coat of arms appears to be the 1917-34 version with the wreath below the eagle rather than going all the way round it.

The eagle refers to an Aztec legend about the founding of Tenochtitlan (now Mexico City). The people were told to settle where they found an eagle eating a snake on prickly pear cactus.
