I cant put the word "imaginate" in a pokestop, when you have to imagine the work of art

[DTrain2002]

That really doesn’t matter here. Clearly, from Street View, it’s permanent. What we’re looking for is info that this is in fact a work of art, such as social media posts from the artist about it, or even a link to a website giving more info on the piece. Proof like this will help prove that the title and description you are providing is accurate. This is info that is encouraged to be included as well:

Art
Works of art are generally eligible so long as they are unique, distinct, and permanent. This can include indoor artwork (framed and murals) and museum exhibits that are intended to be permanent. Nominators should use the official title and credit the artist when possible. They should tell the story of the work, explaining the cultural context.

Submitters should make use of the supporting information section to verify the location and that it is unique and authentic using articles or other key information to help reviewers. In the case of temporary museum exhibits or art installations, consider whether it’s better to nominate the museum or location as a whole rather than the individual exhibits inside.
