This Trident maple belongs to Bjorn Bjorholm

Robert Steven has been presenting bonsai artists from around the world on his timeline. This one features Bjorn Bjorholm of the U.S. (Tennessee). The following is quoted directly from Robert...

"North America Region : Bjorn L Bjorholm - USA
Bjorn L Bjorholm, owner of Eisei-en Bonsai Garden, is a bonsai professional and instructor who spent six years as an apprentice under Master Keiichi Fujikawa at Kouka-en bonsai nursery in Osaka, Japan before receiving certification as a bonsai professional by the Nippon Bonsai Association. His tenure as an apprentice at Kouka-en was followed by three years as artist-in-residence at the same location, making him the first foreign-born working bonsai professional in Japan. During his time in Japan, Bjorn’s works were featured in the Kokufu-ten, Sakufu-ten, and Taikan-ten exhibitions, among many others."

Another of Bjorn's impressive yamadori junipers. The next three trees are also yamadori junipers from Bjorn's nursery
