With the possible win for various heirs of comics creators, the Jack Kirby Estate is going after Marvel. Especially considering they were just bought for billions of dollars.
Kirby tried fruitlessly to get his art back from Marvel for years in the 80s, only to be stonewalled because Editors were selling his pages illegally out the back door. He got a minor stipend from Marvel at the end of his life, but really it’s an insult considering all he did for the company. Now his kids may see some benefits, thought it will take years at the very least if they do.
