I think anything that is on the public domain is free to use without the need of consent from the owner. It is clearly stated on this article[1] works of all media (books, images, audio-video recordings etc) as long as it is on the public domain are not protected by copyright law. This quoted statement from the article clearly explained it.
Q: What is the public domain? What works are considered part of the public domain?
A: The public domain refers to the collection of works that are not protected by copyright, and may be used free of charge and without the permission of the creator or rights holder. Works of all media (books, images, audio-video recordings, etc.) are considered to be in the public domain when they are not subject to copyright protection.
Ideas: Copyright protects the expression of an idea but not the idea itself. Copyright is only available to an idea that is expressed in a fixed form (i.e. paper or electronic media).
Facts: As with ideas, copyright subsists only in the expression of facts within a work, and not the facts themselves. The facts cited in a newspaper article, for example, are public domain, and can be re-used provided that the re-use does not copy the way the author of the article has expressed them.
Works whose copyright has expired: There are statutory rules to determine when copyright protection of a work comes to an end. Copyright protection – the legal right to reproduce, publish, and sell a work – expires after a period following the death of the work’s author/creator. In Canada, the copyright for a work typically expires 50 years after the death of its creator. After this period has elapsed, the author’s works become public domain.
So with your question, as long as the art is not listed in the public domain or not originally created by you, then you need consent from the owner to use it.
