Very high-quality work, which is worthy of attention. I think even after many years this wall will be badly damaged - it will remain graffiti. For 25 of its existence, no one has ever wanted to remove this picture, perhaps it is simply given little or little value. And maybe she looks beautiful and decorates this place. Given its age, it is a local historical landmark.
The whole limit of art is that you do not know what is happening now with this person, and his work still lives. This is his small footprint.
The sun definitely changes the atmosphere. If you include the imagination, then the shadows on the face of this painted person look like something that limits freedom. (restriction of freedom in those socialist times). But despite this - this man is smiling, he is free in thought and no one can limit his thoughts. It's a way of self-expression.
Thank you:)
