A Twin Trunk Ficus....

...... with one trunk on the right developing a 3rd trunk to the rear.  This beauty has nabber (roots) at a nice base, wide enough to support all the trunks.  This bonsai, I think, could be developed into what I would describe as an informal forest.  I don't know if that style exists, but it looks, to my amateur eye, as a possibility.
       The extra are hand craft and fired bonsai pots for a cascade style bonsai, but  it would be rather large as the pots, in real life are about 18" tall.  I didn't pick one up, but I also suspect that they may be from Japan.  (just a guess)
