Hi, I've been trying to get some pics from my contacts in Brazil but with no luck... However,
www.flickr.com is a cool site that may help you as a source of pictures... I've just done a quick search and found the following pic
http://www.flickr.com/photos/viagensimagens/147129710/ . I'm sure there're more around there, you may want to contact the authors of those pics and get more info... Let me know if there's any other thing that I can help with.
