Sotheby’s has released its report in Chinese re-affirming its attribution of the now-disputed scroll purchased by Liu Yiqian for $8.2m last September in New York:

“We have published a detailed and comprehensive analysis rebutting each of the issues raised about the authenticity of the work,” the auction house said in a statement. “This report demonstrates that the brushwork of The Gong Fu Tie Calligraphy is inconsistent with that of a late copy or tracing as was alleged and is of such high quality that it could only have been created by a masterly hand using a soft brush.

Furthermore, we have established that both the seals and colophon are genuine, serving as further proof that the piece was created by Su Shi.”
