I am not sure I remember it right, but at one point (years ago) I got a vector rejected saying that smileys are not allowed because of copyright, and I should change the color from yellow to something else. So I don't know. But if these are exactly like whatsapp icons, I doubt it is legal. Isn't it possible that it's just very similar to that?
I looked at other images in this portfolio, and all descriptions are like that. I wonder if it helps you with the search engine, or what's the point making this kind of description (fx.: World map vector. World map abstract. World map image. World map picture. World map design. World map illustration. World map vector. World map eps10. World map sign. World map icon. World map symbol). Anyone knows?
