John Kirby's Japanese white pine (Pinus parviflora var Kokone) in a Haramatsu-Tosui container and on a perfectly matched rosewood table by David Knittle (you can see the whole tree and table below).

More from the MABS website, continued from above….
“Renowned international professional bonsai artists present lecture/ demonstrations, workshops, and critiques of bonsai. Registrants have weekend-long opportunities to observe and spend time with the artists at breakout sessions between demonstrations, and to view the MABS member clubs’ Bonsai Exhibit.

In addition, a wide range of bonsai vendors are on site offering a large selection of bonsai, bonsai-related plants, containers, tools, books and other supplies. Each featured guest artist presents two lecture/demonstrations. Each bonsai creation is raffled following the completion of styling by its respective artist.  There are also silent auctions and a very active live auction of donated bonsai materials at the Saturday night banquet.”

I picked this one up off the MABS site. I don't know who the artist is or anything else about this tree, though it looks like a sinuous root planting. My apologies for the fuzz.  I blew it up a bit for a closer look
