ThisWay ThursWay: Clueless in Frisco

About a year ago, I was visiting San Francisco and came across this statue in a nearby park. I know nothing of its origin, its history, nor its maker. Therefore... I am clueless. I stopped and pondered and managed to take this photo with my digital because it was so large and impressive. 

One thing I do know, it's wonderful to have blogger friends that help you along in the blogging world. And so,  I just want to give a shout out and say thank you to:

Any clues? Has anyone seen this statue or know anything about it?  If not, I'll just have to return to San Francisco once again.
