Fun with log cabins

Sisters quilt show, year unknown, originally uploaded by Mellicious.

This picture is out of my mom's photo album - she and my aunt went to the Sisters quilt show, maybe 5 years or so ago. (I was too broke to go, it wasn't that I wasn't invited or wasn't interested!) This is really a great quilt. Do you think it was paper-pieced, or what? That seems like the easiest way to do something like this, but it might not be. No real way to tell.
