Since you are reporting Bilbo's Birthday Parties from all over the world, here are some news from Brazil. We call ourselves The White Council - A Brazilian Tolkien Society. We have more than 3500 members all over the country.
In September 22, the Săo Paulo section of the White Council got together for a Celebration of Bilbo and Frodo's Birthday: The SP White Council's Hobbit Party. We had about 150 people for a Hobbit Picnic, Storytelling (featuring the tales of "The Three Trolls" and "Lúthien & Beren"), the exibition of Peter Jackson's The One Movie in a private DVD session, a Costume Contest, Elvish Dances, lots of contests, swordfight training and other Tolkienian activities. We also had a Used Books Campaign, hundreds of Children's books were donated by our members for an Orphanage.
We are sending some pictures attached... not very good, I fear. I (Shelob) am the one in the short black dress. Greetings from Brazil!
Shelob - Cultural Director of Brazil's White Council.
