I recently came across an image of Axel Erlandson standing next to an amazing shaped tree. I did a little searching and found out that Erlandson created what was once known as The Tree Circus in Scotts Valley, California. Unfortunately, The Tree Circus went into disrepair after Erlandson's death and multiple owners. Some trees still exist at Gilroy Gardens in California. Before the Tree Circus was dismantled and destroyed, Mark Primack took the time to photograph and record the specimens. You can view his website here. I found some pictures from when the Tree Circus was featured in Life magazine, but there was no accompanying article.
