The International Collage Exchange is the brainchild/project of Dale Copeland of New Zealand. Full explanation can be found on her site, outofsite.co.nz.
I have been participating most years since 2004, when I first discovered it, and have accumulated a fantastic collection of collages from artists around the world. I have been very sporadic about documenting the pieces I have sent, but here are the ones I have been able to find thus far.
