I was commissioned by german advertisers "Polarwerk" to illustrate a massive urban landscape as a campaign motive for their client GEWOBA, a housing society in Bremen, Germany, that turned 90 years. Luckily the image was liked so much they put it on a tram wich is still running in Bremen until today. Also, my drawing arm is still hurting from this job until today. ;) Please have a look at the whole image and close-ups at GEWOBA's website: http://www.gewoba.de/wimmelbild/gewoba-90jahre.html
