Not an official insignia: This sign or flag should not be considered official.
It is just a proposal of an artist (drawer), and it is not in any official use.
This flag is fictitious, proposed or locally used unofficially but not adopted. It may be named as it would be as an official flag of a geographical or other entity and have some visual elements that are similar to official logos or flags of that entity, but it is not official and doesn't have any official recognition. Under any circumstances whatsoever, you should not add these flags in any articles, unless it is proposed by a government agency or it is covered by the media or if the flag is locally used.

විස්තරයChola flag official.png
தமிழ்: சோழர்கள் தங்கள் கொடியில் பாயும் புலியை வரைந்திருந்தார்கள். கொடியின் பின்னனி நிறம் சிவப்பாகவும், புலி மஞ்சள் நிறத்துடனும் இருந்திருக்க வேண்டும் என்பது ஆய்வாளர்களின் அனுமானம்.
English: Translation: The Cholas had drawn a tiger flowing under their flag. Analysts speculate that the background color of the flag should have been red and the tiger yellow.
This is not the official Chola flag, but a modern imagination of what the flag used by Cholas would look like. It has no historical background (no historical information on the shade or hue of the color, the angle of lines, the curvature or straightness of lines, etc). No flag artifact or any archaeological proof of a flag used by Cholas survived.
