Visually-impaired users, like most users, may want to know what a logo looks like. It needs to be accessible, but in most cases of non-free useIf it must beis in thean infobox although, the infoboxlogo is inaccessible to visually-impaired users.Aand, in that case, a prose description is therefore appropriate. That would normally be by addingBecause an [[alt attribute|alt text]], but that would not work in an infobox. Instead, add the prose description to the body of the article. Since the logo is a [[Wikipedia:No original research#Primary, secondary and tertiary sources|primary source]] and logos are rarely described in secondary sources, in a Wikipedia article a logo may be described directly from the logo, factually but preferably with prudently understated wording, to avoid its reading like [[Wikipedia:What Wikipedia is not#Wikipedia is not a soapbox or means of promotion|advertising]].
