Get a unique mural! I do wall paintings for private individuals and companies in egg oil tempera.

Egg oil tempera is a non-toxic paint that has a significantly lower environmental impact than a plastic paint. It also has a special sheen despite being very matte. Egg oil tempera can be painted on any surface.

The cost depends on size and detail, but does not have to be more expensive than a nice wallpaper. Let me know what ideas you have and I can come up with a proposal that fits your budget.
