There are two bone china sets of “a cup and saucer”, made by Noritake, for sale on ebay, that are based on this series, “A gentle noble’s vacation recommendation” (that’s the actual name of this series). They’re around $160 US dollars, and I can’t find a trace of their existence elsewhere.
If anyone can recognize the family crest displayed on the teacup, please let me know who it represents. I’m really curious, but I don’t feel like rereading the entire series just to find out. Also, please let me know if there’s an official store website selling these. I couldn’t find them on the official Noritake website (they only had “my neighbor totoro”).
