Five double-decker London buses have been wrapped with images of the service that gives people directions and transport information around London.
Printing of the jobs was handled by Reading-based VGL, which used its Durst 500 machine to print the wraps.
Jason Cotterrell, country director for CBS Outdoor UK, said: "London’s agenda-setting, technology-savvy audience is a perfect match for this campaign from Google.
He added: "The campaign also benefits from the scale, movement and overall impact of buses ensuring their presence is felt on all of London’s high streets.
"It’s this combination of audience and unmissable impact that has established bus ads as the best way to be seen in London and in all of the UK’s urban areas."
The buses will take in a variety of routes across the city, including the Number 19 through Clapham, the West End and Highbury & Islington, as well as the Number 8, which passes through Holborn, Liverpool Street and Bishopsgate.
According to James Rothwell, marketing manager at Google, using London buses was "the ideal platform to create awareness across the city".
