That takes a while to get it though. I imagine they are going to be experiencing a very high demand right now. I have one in a box at my mom's house.
Same goes for the Whitehouse. You can get one that flew over it too, Congressman can probably help you with that as well. They have small flag poles on the roof of the buildings. Someone has the job of raising the flag, bringing it right back down, and passing them out to the Congressmen. Then you get a flag that was flown over Congress or the Whitehouse. Pretty neat.
