It looks like it may have been a day room at some point.

I usually hate tagging and graffiti in places like this, but I love the sequence of angels sadly going up the stairs, it's quite poignant in a place like this.

I'd imagine that if I were ever committed (which I SHOULD have been in my teens and early 20s, but because I wasn't "openly" suicidal, my mom couldn't commit me, even when I was under 18 and she was still my legal guardian), my walls would be covered like this, with clippings and my own artwork...though my bedroom walls do kind of resemble that already.

It's the Coppertone Room!
