What is this backdrop made of?

It is a printed photography backdrop, typically a fabric or fabric-like sheet. It is designed to hang behind a subject, not to be worn or used as a wall covering.

Can I use it for a family Christmas photo?

Yes. The fireplace-and-tree scene is built for exactly that kind of portrait. You will still need a stand or frame to hang it and some space in front for people.

Does it include a stand or frame?

No. Backdrops of this kind are sold as the printed sheet alone. Plan on a backdrop stand, clips or a wall mount.

How do I remove fold creases?

Hang it taut and let it relax, or gently steam the back side. Avoid a hot iron directly on the printed face.

Is it the same as a real fireplace scene?

No. It is a printed image of a lit fireplace and tree, so it reads as a backdrop rather than a three-dimensional set. Keep the subject a little forward of it to reduce shadows.
