Understated elegance from Willi Benz. This stone hails from Pennsylvania.
Both Willi and Gudrun had suiseki on display, I've only managed to capture Willi's entry. Also, as Gudrun already has her pic in an earlier post, and as I didn't get a chance to nab Willi for a photo op, I decided to post a photo of his suiseki instead.
That said, I believe it was Gudrun's stone that won a prize at Lorca.
