Memorializing a Town of Memorials?

So I've been a bit flummoxed about what to do with my bathroom. I moved in with all white bathroom towels, shower curtain and rug (remember the pink bathroom?), and was planning on doing a sort of chic french sort of look, bringing in some black accessories, including a black wire mannequin earring holder thing I got for Christmas. That all changed when I went to Bed, Bath, and Beyond and was forced to buy the DC Metro system map shower curtain. I know the typical way to decorate around that would be to pull out the primary colors and go crazy. The bathroom is the one space you can really do that, but for some reason, I just can't get a good picture in my head of what it should look like. It also doesn't help matters that the tiles on the floor and in the shower are white with the occasional brown tile. If it weren't for that stupid brown tile, it would be a different story. But anyways, I digress. My idea was to try and make it transportation themed of some sort, and so I made a basket out of extra maps I've had lying around, with the intention of making more, but that has yet to be seen. And I still couldn't picture how to pull it all together.

Enter this month's edition of Real Simple/a random blog where I saw the same thing. I love graphic posters, and the travel posters for state capitals by The Heads of State are fantastic. I like them all, but I thought, why not go all out and DCify my bathroom? I'm thinking this:

and this:

I've been wanting to get the Ork poster for a while now, and this just gives me an excuse. :) So my question is, does this constitute an overly kitschy-themey bathroom?
