If I want to buy all rights or ownership to an existing cartoon, what information do you need?

Just provide information on the size of your corporation or business and how you intend on using the cartoon, do you want to use it to represent your company or business? Will it appear on all packaging, logos and your web site and social media in perpetuity? Will the cartoon be used in your marketing materials and print promotions? Knowing these aspects will help greatly. Keep in mind there are other ways in which cartoons may be used. For instance, on your web site. This means electronic cartoon rights would apply so there are many variables to keep in mind.
