I do not know the artist or the name of the painting, but I can remember slightly what it looks like, it is of a skeleton with a crown on strapped into a chair with white flames burning him and there is another man in the background/off to the side that is looking at him, if anyone knows of this painting or has any ideas on what it is I would be very grateful:)

Megadeth has a cd cover of something slightly like that, you might want to check it out... you never know...

I also know that it is a famous painting but that's all I know

Then I am of no further use... I have no clue whatsoever about art unless its music... sorry dood...
