Probably the largest piece of street art in LA; a stencil-based train that stretches 380ft.
Assisted by Bumblebee, M-City completed this wall in 4 days.
It's striking from a distance, but also really special up close: the smoke streams are incredibly intricate cityscapes.
M-City was in town for a show at the Carmichael Gallery, which included stencilled canvases and some really stunning machine-like installations.
"An old tobacco factory in Madrid seemed like the perfect place to do a proper (and properly sized) tribute to the classic Optimo Sign, with smoke and all. This piece is very personal as it talks a lot about where I come from and the influences in my work but at the same time it gives an optimistic word to those who might not know the context behind the piece."
