I got a few printed recently, but not for taking out.
I plan on getting a few more large sized ones latter, along with a number of smaller one.
the main factor in deciding was image resolution, which means going with scans of official artwork, which is what I'd prefer anyway.
I tried hunting down posters of her before, but with no luck, it involved spending a good deal of time trying to figure out which megami magazines had posters of her, after narrowing it down I bought a bunch, and struck out completely.
I'm sure if I had a photo in my wallet, it would get ruined over time.
I had one in my psp case, and a bit of rain turned half the image tie dye.
I stopped taking out the minifig/keychian I have of her, out of fear I might loose or damage her.
I'm thinking of going with fanart for the smaller frames I'm gonna hang around my room, mainly going with those that really bring out her charm.
