My photo depicts a street art next to STAIRS leading to an underground passage. The GRAFFITI is quite fitting, as it portrays a TRAM (and what's the difference between the RAILROAD for a tram and one for a train?...)

The passage must have been a scene for real artists, as there are more paintings like this there. Too bad other "painters" don't appreciate the art and their own, not so artful, marks on the walls...

STAIRS + RAILROAD = GRAFFITI
