This is a set of three postcards featuring designs by Yoshitomo Nara, a representative artist of contemporary art: "Puddle Flowers" series 1, 2, and 4. All of these are already out of print and are extremely valuable. They are new, unused, and complete with all included items such as seals. In particular, series 1 still has its shrink wrap intact, except for a small part on one side. There are almost no opportunities to acquire a set of three in this condition, so please consider them for your collection. Furthermore, series 1 and 2 are particularly expensive, with even copies showing considerable wear being sold for over 20,000 yen each on Amazon and at specialized used bookstores. This set of three is priced considerably lower than the market value, so if you've been looking for these, please consider purchasing them.
