Huge Ginkgo seed sculpture in Oregon

A huge Ginkgo seed "Ginkoberry Gwa" bronze sculpture by NYC artist Ming Fay at the Oregon Convention Center (MLK Concourse -Ginkoberry-), Portland, Oregon.

The interior street which joins the Oregon Convention Center has two 14ft high bronze Ginkgo seeds installed on the north and south entrances as the "pillar of time". Above them are three clusters of Gwa flowers (American mythological Gwakalekala tree).
The artist was inspired by the Ginkgo forests of prehistoric Oregon.
