I certainly hope that this is not all of the people that were there but maybe the spiral is more popular. Let's see.
So 5 people in total. But this is just one picture. But considering the abundance of pictures from Brasov I can only interpret the small number of photos is that there were very few people and they were ashamed to put up more. But that's just my theory.
But let's see the spiral.
In the second picture on the left we can see a man in an orange t-shirt with wavy hair and on the right a bald man and a blond woman in a green t-shirt in the center. These are our reference points. These people can be observed in the wider picture where we can see the whole spiral and we can estimate the center of the spiral is made up of 8 people, and we ad to this the number of people that can be seen in the bigger picture 15.
So let's give them the benefit of doubt. Lets double the number of people in the big picture. Even so we get 30 people. That's very few for a big city like Arad.
