If the mural has any copyright at all, it was initially owned by the author, but the author may sell his or her copyright to others.
This is called a copyright assignment or transfer of copyright ownership.
First, the author generally retains the copyright unless other agreements are made. Second, the duration of copyright protection is based on the death year of the author.
Under US copyright law an independent author or artist must intentionally contract in writing to lose ownership of the copyright of his or her own creative works. A copyright in your own work of authorship is a personal right and should not be "automatically" transferred to (or "stolen" by) others.
Initially copyright protection is instantaneous as soon as the author has fixed his/her story in a "tangible medium". If formal registration is deemed necessary the author, or his/her agent will have to contact the Copyright Office in their area for instructions.

French copyright is the droit d'auteur, or "right of the author." However, the word "copyright" is increasingly used.
Only if the copyright is not part of the copyright registration that is copyrighted in the publication of the author's registration. But If the copyright is part of the copyright registration that is copyrighted in the publication then the copyrighted author of which publicized the copyrighted registration is not copyrighted in the legalized sense of which a publication is copyrighted. Yes, a work is always copyrighted, before and after editing and both versions.
The author of a creative design is the owner of the copyright automatically.
