Laminated Autographed Movie Posters?
 

I recently purchased some autographed movie posters, and a few of them I received were laminated with some kind of thicker backing also. The autographs on top of the lamination.

Has anyone heard of this? Are these as collectible as non-laminated posters? It said nothing about it in the auction, so I'm wondering if I got my moneys worth.

Let's not even get into the issue of whether or not the auto's are real or not. I'm just going to go about my life assuming they are real :D
