Testify Brothers!!!
It is hard to describe the feeling of being in the presence of such amazing Bonsai from so many Artists from all across the USA!
I agree it should be about the tree. In Japan it is for the most part because there are so many recognized artists who work on so many trees that belong to a third party, that this is custom. But in America there is a slightly different picture. As things are now we have more artists trying to achieve recognition for their work at different shows where many will take exception when someone comes with a "ringer" and passes it off as his/hers own work. It is kind of a bonsai plagiarism. When awards are given for best new talent and things like that, and the winner in fact has a bonsai styled by Kimura or someone else it tends to not only cloud the issue but creates some really bad feelings.
One way you can look at it is as if there are two perceptions of a bonsai show. First would be like a dog show where no one can take credit for the dog, it is what it is, the owner gets recognition for having the dog, not making it. Second would be an art show where the artist paints a picture of a dog and gets credit for artistic accomplishment. Another way to look at it: One is judging the journey to get there, the other is judging the result at the destination.
We are kind of torn between these two ways of looking at things. It does not make either one bad or irrelevant the only problem is when we try to mix the two where someone is always trying to game the system. Is your show about wonderful trees, or is it about recognizing artistic achievement? Issue arise when someone from the wonderful trees camp decides he/she wants recognition from the artistic achievement crowd by entering a tree designed by someone other than themselves, but claims it is their own work. Often this boils down to what we used to call the victory of the check book artist.
Point in contention: If you desire recognition as an artist in your own right then it is incumbent upon you to produce your own entry, or at least kept a third party tree alive for several years and or made significant changes to it. If in your mind it is about the tree sign on the dotted line till your 401K goes in the red and enter the wonderfull trees contest.
