TCT: Section 1, Constructed

Just a quick (and boring) update -- I finished construction of the first section for the Texas City Terminal shelf layout.  I'll post up pictures soon. I can't decide whether I should start laying down roadbed on the first module or start building the second module.  Hmmm... decisions decisions...

I realized I also have a challenge on the horizon.  I read over Iain Rice's description of how he had handled the backdrop.  He mounted it on the wall behind the shelf.  I don't want to do that (nor would my wife likely appreciate that either) so It's up to me to figure out how to handle this.

For portability's sake, I'd really prefer if the backdrop was detachable.

I've come up with 3 solutions:

1.) Backdrop Stand
It's possible I could build an L-shaped setup which the shelf layout sits on which also holds the backdrop.  This doesn't seem like a good idea from any perspective.

2.) Re-enforced Back Plate
Right now, the place where any backdrop would mount onto the section is 1/4" ply.  That's thick enough to build the shelf section out of because it fits together and develops strength through jointery, however there is no way that would be structurally sound enough to hold a backdrop.

I'm imagining some kind of re-enforcement would be needed, perhaps another layer of 1/4" plywood or even 1/2" ply.  To that would be mounted some kind of backdrop holders.  This is probably my best option but needs some serious design work.

3.) Don't Make it "Easily" Detachable
I could partially give up and make it so that "detachable" means "the drywall screws holding in the backdrop can be unscrewed by an impact driver".  This has the bonus of being far less complex, and how often is the backdrop going to need to be taken off anyways?  There's some potential here.
