This is a HAY PHAIDON art book. I purchased it at the HAY flagship store in Omotesando, Tokyo, when it was published for the 20th anniversary of HAY. I used it as a reference when I was replacing all my furniture, but I haven't had a chance to look at it since, so I'm putting it up for sale. I've only flipped through it about three times, so the condition is good, but please understand that it is not new.
