1. it is a logo of a public high school with a wide influence; 2. the logo is only being used to identify the school in question; 3. its inclusion in the article adds significantly to the article because it represents the subject of this article. 4. the inclusion of this logo does not prevent or reduce the copyright holder's ability to utilize their rights. 5. the resolution is low due to copying and compression, so it does not substitute for the holder's original works.
