Lisbon's Municipal Council did something really nice.
They arranged for this really cool space for graffiti artistics to do their thing. The artsy graffities, not the tags and other scribbles.
They say it is a "Garrifit and Street Art Galley supported by the Câmara Municipal de Lisboa and dedicated of creative freedom as expression of urban art."
These are two of them. Great colours.
