It's not often a framer's label can give you a good indication of the quality of what's framed, but in this case, it's a pretty good hint.
Read up on the guy:
This is the welded aluminum frame he designed for MoMA. I'm not going to pretend I know who the artist is, but I know it's something good. At the very least it's a serigraph, at best an original. Can't wait to get home and research this.
