Actually, it's just an improvised stall, meanwhile it will not look like that anymore, because at the NDSM shipyard a lot of graffiti artists "join hands", so to speak.
If someone does not know it yet, the NDSM shipyard is a kind of art center where many artists have found space and space to create new works, but also to sell to the numerous tourists.
If ever someone is there, from the train station you can get there very easily with the free ferries.
