Always cool to see this kind of buildings (subway ventilation, or electricity...) being painted. Otherwise it's all grey without windows, quite ugly... but with a work of art it changes everything as we can see on your pictures. Thanks for sharing these pics on The StreetArt Community.
It is beautiful that they beautify these sites as they should. So should they do with every site where there is room, to make it look beautiful. I'm glad you will like it.
Always a pleasure to show those found sites @heroldius 🤗✨.
