Like any other modern city, Mexico City has malls, commercial centers and hypermarkets spread out across town. In Centro Histórico, where space is more limited, it's a different story. Travelling vendors circle the streets, offering their products and services. Small workshops and hole-in-the-wall businesses are set up anywhere possible. These small shops and workshops often don't have any partitioning walls or doors that part the public from the working staff inside. Passing by, one could witness the production first hand and taking one step inside, you're part of it.
I was struck by the beauty of the machinery and the personalized workspaces visible from the street. All I had to do was to take one step inside.
