A classic US rural/residential mailbox, in black, standing on plain crossed wooden posts. This is a typical design of mailbox in North Carolina; If you've ever been there you'll see mailboxes like this EVERYWHERE! ;-) When placing mailbox next to a driveway, make sure that the right side (the side with the flag) is facing the driveway.
Feel free to reskin this mailbox at your leisure. Just make sure you follow the terms of my license.
UPDATE 5/25/08: Welded some vertices together, decreasing polys and fixing texturing. Enjoy!
