Even though they look like they'd be more at home at the Best Exotic Marigold Hotel than they would on the streets of Wild Style, LATA 65 is probably Lisbon's most interesting graffiti gang. This urban workshop lets senior citizens learn under the tutelage of some of the Lisbon's most accomplished street artists. The group's murals have been popping up around Portugal's capital and are brightening some of the city's more neglected neighborhoods.

MessyNessyChic has more, as does LATA 65's Facebook page. The group says their aim is to democratize street art by reaching out to different age groups and letting everyone try a form of expression that is usually reserved for the young. If these amazing photos are any indication, it looks like that mission is accomplished:
