The picture, taken by the Swiss photographer Tiziana Vergari, has caught the eyes of hundreds of internet users.
Everyone is wondering, how many girls are in the picture.
The answer is not that obvious. The author has not given the answer so far.
The opinions vary. Some say, that there are three girls sitting on the bench, other say that there are up to 13. And how about you. What number do you pick?
Pay attention to all the details: hairstyles, the way they sit, folds on the clothes.
Perhaps those are twins.
