This is an autographed shikishi board by Sachiko Kamachi (Izumi Sakai of ZARD). I had a habit of collecting autographs around 2012, and this is one of several items I purchased at a high price on an auction site. Regarding the condition, there is some discoloration and warping, but I think it's in good condition considering the years that have passed. I believe that aging deterioration is unavoidable, so I would like to sell it to someone who understands this.
