ATD and Japonese Swirls in the UV MC - What are the diferenc

[armindo__dias]

I've been wondering whats the deal between the ATD and the Japonese swirls in the UV MC. From what i've seen the Japonese ones have more yellow and pink colors while the ATD ones have more intricate veins and more mixed colors.

Now, was the lot of UV MC's divided between ATD and Japonese for painting? Who painted the most?

Last, but not least, is there any diference in collector's value between these two kind of swirls?

Thanks,
