This flag is fictitious, proposed, or unofficial, although it may look similar to an official flag. Such flags should usually not be used in articles, unless they are in widespread unofficial use.
The factual accuracy of this flag is disputed. The sources are likely unreliable, the first is a blog containing several Turkic flags, several of them fictitious and unsourced. The second is an image on Flickr claiming to be the flag of the Ottoman Empire in 1517, lacking any source. The third is about the history of Hungary, also containing the flags of Hungary, this flag is used in the section about Ottoman rule, but lacks any source or caption about it. The fourth is a Facebook post about Ottoman flags since Osman I, it seems that its source is the blog previously mentioned. The fifth is a page about the flags of Cyprus, it is lacking any source.
