I purchased the official exhibition catalog "Kocchi datta kamo shirenai" (It Might Have Been This Way) from the Yoshitake Shinsuke Exhibition at Yokohama Sogo. It's 16cm x 12.5cm, and about 4.3cm thick. It comes with a vinyl cover. I may change the shipping method to Rakuraku Mercari Bin. Thank you for your understanding.
