Sci - Fi or Fantasy

I had to return some books to the Metropolitan State University library. Completed that task and then turned around to find these fun things:

The library had these on tables with a book collection labeled: "Sci-Fi or Fantasy?" Whether you think these are sci-fi or fantasy is not the main point. I think the main point is that this library is not "stuffy." Perhaps "stuffy" doesn't translate well into all the cultures and languages of my readers. Hope you all can figure it out!
