I know that this solution will not satisfy the purists out there, but for those seeking function over form, there is a company out there called BallQube which makes crystal styrene display cases for sports memorabilia and other collectibles. The Eagle is a perfect fit in their football case, which is also available now with a mirrored back and/or wood base. The prices on the website are a little high but the items are widely discounted on E-Bay. I paid $13.00 for one at a collectable show.

It's no where near as nice as the wooden case that Rich made, but it keeps the dust off.
