Black Bear ukuleles are made by Duane Heilman in Yukima, WA. He has made some very unusual ukuleles in his time. You can see a selection of them on his site with the most outlandish being this Picasso ukulele. Duane used to regularly sell new ukuleles on eBay and through his own site but he's been very quiet for quite a while now.
