I have noticed that this type of street art exercise is being put into practice in several countries. In Latin America, I have seen documentaries of interesting works made in Brazil, for example. I think there's also something in our country, Venezuela. In fact, it is a very valid proposal that promotes the relationship between the ordinary citizen and art. The painted image is very well captured in your photograph, and being a grandmother that sepia effect looks very good, as well as that angulation in counterpoint. The stairs are so symbolic; I got the image of the famous Odessa stairs from Einsenstein's film. Greetings, @velimir.
