Purchased over four years ago from "Taisei Bijutsu" on Yahoo Auctions, with a guarantee of authenticity. As I am an amateur, the actual authenticity is unknown. It is large, approximately 220mm tall and 80-90mm wide. If you have any objections regarding authenticity after purchase, please lodge a complaint with the relevant dealer. It is said to be a work by Zhang Daqian, and this is an offering at a price that is a significant loss compared to the purchase price. I have kept it stored away since I bought it, so I believe the condition is good. Thank you.
