Yes, I should have written down more information on who made it. I don't remember who it was. There is a character written in the art object but I think it translates as something like "frog pond" as I recall.

yes. my friend @lightsplasher, I think it's only natural if a friend doesn't remember about the information and the creator, because this painting has been made for a long time and even took a few years ago.
