wire are recesse
This was my first thought as well. The pot is well made, has a lot detail and recessed tie wire holes. This leads me to believe, maybe incorrectly, they've been making bonsai pots for a while. I've check several sites with list of bonsai potters, searching for something similar in first or last name, from around the world with no luck. Was hoping maybe someone had another with the same signatureROND is what I see in it.
Bond.... James Bond.It could also be a B. It may just be a one off, or someone who made a few then stopped. I have one signed Kravjansky, and haven't been able to find any info.
