Salvador - Bahia - Brazil
Traditional celebration of Senhor do Bonfim
Wow look at all that white, it must be an extremely large and important event that takes place in the sender's hometown of Salvador.
I thought this stamp was interesting and did some digging up on it. The stamp shows "Marco Zero" a monument found in Macapa. Macapa is a city on the equator and every equinox, it is possible to see the sun through the hole on top of the Marco Zero. When this happens, it's as though the invisible line of the equator is "visible" for a short period of time.
