I bought some of that stuff new. I ended up slicing a slit in the top to get the cards out. It "destroys" the jumbo card, but not so much that you can't still enjoy it from the front. A lot of guys I knew were tearing them apart to get the cards on the inside.
I don't remember now, but I think you got base, inserts, etc from inside the jumbos. I doubt there is too much interest in the jumbos unripped, although a player collector certainly would want one of his guy unripped if they didn't already have one.
I assume I saved at least one Frank Thomas jumbo at the time. I know I usually saved at least one of any unopened Thomas stuff (Donruss tins, etc) I came across.
