Wei Tianchi (1936.4-) is a native of Dangshan County, Anhui Province. I studied under Mr. Shen Zishan and Mr. Lin Sanzhi. Calligraphy studies seal script, official script, cursive script, calligraphy, especially good at calligraphy. Calligraphy style is vigorous, elegant and unique. Now he is the consultant of China Calligraphers Association and the chairman of Jiangsu Calligraphers Association.
As for whether the photo is his original, I'm not sure, because I'm not good at it.
I hope I can help you.
