I will mail you or anyone you'd like a personalized postcard from Rio de Janeiro. You can either tell me what you'd like the message to say, or I can write something of my own making. Just let me know the occasion! I'll show photo proof of me mailing it when I deliver the gig, and then you should have the results in your mailbox in a few days!
If you want, I can you send the post card in an envelope but don't write anything on it. Then, you can write on it with your hand writing and mail it back to me and I'll mail it from Brazil to whoever you want me to.
