tips on hanging foamcore?

[anairdna.livejournal.com]

ok, so i have a collage on foamcore thats odd-sized, so i cant find a frame for it(and i dont have the time or cash to get it framed). i need to figure out how to hang it by probably 10:30 tomorrow morning.(its a long story on why the short time frame)

ETA-its going to be hanging on a brick wall(or possibly leaning against something on a table) just for tomorrow night.

i have no idea what to do, short of maybe gluing some shallow brads into the back and tying wire to it....

any advice?
