Mobile billboards promote Proms
They took part in a 10-day marathon of free live music events around the capital, which led to orchestras playing in hospitals, railway stations, shops, a museum and an airport and on a train.
Look Media sent four walkers out to Spitalfields, Paternoster Square in the City, Covent Garden and St Pancras carrying the mobile billboards, which have one poster on the back and another, smaller one, on the front.
They also handed out Oyster travel card wallets with information on the BBC Proms, which run until September 13. They also transmitted Bluetooth messages to passers-by's mobile phones with a clip of music and a calendar of concerts.
Look Media has also carried out promotional work for Betfair (pictured).
