Back when I was creating the initial set of four pin frames (Millennium Celebration, Celebrations, International, and Figment/Mickey/Stitch), I had a few 2000 specific pins (and artifacts) left over and wanted to see about fitting a fifth frame into that collage. And so Millennium Celebration Two was created and made part of the set.
The problem with the frame was that, besides one or two really great pins, the rest of the frame was rather bland... When the collage was taken down for me to move to Celebration, it was quietly retired (along with the rest of them), with only the original Millennium Celebration frame to be resurrected with some additions.
The other frame was pilfered for these additions as well as another concept - one featuring a Tapestry of Nations T-Shirt, that never really came together well.
In either case, with acquiring a few new 2000-era pins and artifacts, I've decided to resurrect the second Millennium Celebration frame. And here it is...
