frog

We have been actively searching for any information regarding its purpose. its age, its history or its value
for over a year now-to no avail. It is an odd shaped heavy ceramic shallow bowl. It is Painted Bright Red with Yellowish spots (almost like spatter paint) on the outer rim which has a line of raised bumps along the middle of the top edge. As you can see, there is a frog perched on the edge of the bowl in full relief which appears to be watching the scene painted in the inside of the bowl with rapt attention.The inside walls of the bowl are painted black. The inside bottom of the bowl is painted with a gloss white, it features a hand painted outdoor scene featuring a dragon going upward which entwines itself throughout the scene behind the 5 different people painted within the scene.The bottom of the bowl on the backside has a blue 6 character Chinese Mark in the middle. We have our own theories about story it tells, but we have no idea whether this is new, old, where it came from, or what purpose it was created to serve. It is beautiful-with Bold Bright Colors-Kutani Style? We would appreciate any help with identification, history, value, etc. Thank you
