(IANAL) Also since your "work" will likely have some copyright since it itself a derivative work, I would go with the CC0 license so that others can use your work without fear of infringement of _your_ rights. https://creativecommons.org/share-your-work/public-domain/cc...
"CC0 helps solve this problem by giving creators a way to waive all their copyright and related rights in their works to the fullest extent allowed by law. CC0 is a universal instrument that is not adapted to the laws of any particular legal jurisdiction, similar to many open source software licenses. And while no tool, not even CC0, can guarantee a complete relinquishment of all copyright and database rights in every jurisdiction, we believe it provides the best and most complete alternative for contributing a work to the public domain given the many complex and diverse copyright and database systems around the world."
"Metropolitan Museum of Art: All public domain images in its collection are shared under CC0, which expanded their digital collection by over 375,000 images as well as provided data on over 420,000 museum objects spanning more than 5,000 years. Through the power of the commons, billions of people are now able to enjoy the beauty of the Met’s collections as well as participate in the continued growth of the commons, utilizing the infrastructure that makes greater collaboration possible." https://www.metmuseum.org/about-the-met/policies-and-documen...
