I used to keep all of my OS stuff in binders, but I switched to toploaders due to the pages warping some of my cards.
Good idea, as binders do present a problem.
I am a very "visual" person and need to see everything. Otherwise, out of sight, of of mind. Consequently, my surroundings are very "busy." This might make things even more confusing, though, which is I must always strive to adhere to the adage "A place for everything, and everything in its place." This is why all of my WP have to be in one place - in my case, my attic. To maintain order - and my own sanity. And even though I might not be able to see, say, "Frosted Snakes," I know it is inside the binder labeled ANS1 - which I can see. It's in plain view on the shelf.
To me, though, this is not "displaying" Frosted Snakes. Or, let's say, it's not doing the title any real justice. If I were to display Frosted Snakes, I would have a separate shelf or deep glass-covered frame housing the original title, a copy of Jay's original rough, the mini cereal box, the eraser, and the Kooky Patch. I would need a veritable museum, though, to do this with everything.
In my opinion, "displaying" means to put something out there for everyone to marvel at, behold, and appreciate. Like paintings in a museum. If they took all of the paintings, though, and slide them all into vertical compartments along a wall, I don't care if the compartments were made of marble or mahogany edged with gold filigree, it still wouldn't be much of a display.
As far as displaying your entire collection, I'm afraid you are in the same boat as the rest of us: Shelves, cabinets, closets, etc.. Even if you had an entire room devoted to WP, this would still probably be the case.
Again, though, I'd recommend taking a small handful of your favorite WP and displaying them like works of art (which they are) in a museum. Make it impressive, though. Top loaders and binders (in my case) are great for storage, yet don't exactly set the world on fire. (Case in point: Your "Gums." I noticed and admired it because it was on display. What i didn't get to notice and admire were the hundreds of other titles inside the top loaders and binders.) Also, you could also switch out your displays from time to time, have an open house, and invite us all over for cocktails and hor d'oeuvres. (Or maybe just keep it simple and BYOB.)
