Hi all, Long time reader but first time poster, so I'm sorry if this isn't the right location / forum. I'm trying to find a specific tsuba by Funada Ikkin (船田一琴) which depicts Mt Fuji. I have attached a picture. It used to be available at Aoi-Art but the listing was taken down recently, and the owner told me that it was sold. I was wondering if any of you had advice or recommendations for antique buyers or brokers who may be able to help me make an offer on this tsuba? Thank you!
