Any hobby that starts slabbing and specific grading by so called experts, is inviting problems. Yes they already have something for movie posters, lobby cards or fliers. It's called a frame.

Why does a buyer need an outside source, which it is important to point out, offers no guarentee as to the grading, and which may have an interest in the values, to tell that buyer what's enclosed in a plastic case which can't be opened for examination?

Here's the answer for the next time slabbing and grading come up for anything new. Look what happened to sports cards. Look what happened to coins. Look what happened to stamps. Then ask if you want your hobby destroyed by grading and slabbing.
