Are some of the original Muppets at the US Copyright office?

I remember reading just for the sake of it, just for fun as the Muppet nerd I am. lol And I noticed a lot of the characters would say the claim would be a puppet. So I'm wondering in the Copyright storage or however they do things there. Is it possible that a lot of these original Muppets are still there sealed in some sort of box? I thought they all went to Atlanta?

Many of Jim Henson's creative works are on long-term display at the Center for Puppetry Arts Museum in Atlanta:

The Jim Henson wing is expected to be completed sometime in 2014.

I can't wait to see that Jim Henson wing, 700 of the original puppets, props, etc. I'm so excited. I would travel to Atlanta just to see that too, plus I think I got some family near that area, but mainly to see that. How are they doing to make it? I heard it was going to be like a walk in tube almost like a glass walk through aquarium but instead the original Muppets on racks or something like that. I'm not sure if I read that somewhere or that's what came out of my own prediction. Either way, it's going to be awesome
