Their Demon Mascot grew from that painting, and continued with the bridge in Terrible Certainty, and the carved forehead of the Demon etc. - all seen on T-shirts around the world now for years. Finally after the sales of hundreds of thousands of T-Shirts, he decided to contact them about instituting an industry standard royalties contract:
"I asked no more than any cover artist would receive, and offered to forget the entire 25 years of sales up until my notice of copyright. Their producer and ex manager Karl Walterbach refused to discuss it, warning me not to disturb the band, and was really arrogant and even insulting."
"Hello Pilipp, You are getting on our nerves. Mille will not respond to your absurd & ridiculous claim. if you think it has substance go ahead and start legal action. karl"
"They'e hoping I'll be afraid of an expensive lawsuit against them. Even if I spent years, and thousands of dollars, they can afford lawyers much better than mine... but they can't buy public opinion, or the truth..."
So, he decided to tell the story to the fans, and ask their opinion. What would you do in his place? Please add your comment on his Facebook post - you can read the early responses here.
