Optical Illusion Billboard Inserts Missing Children Into The Background Scenery
Creative advertising uses polarizing film to highlight plight of lost kids.
To help draw the problem of missing children into the public light, German agency thjnk came up with a set of creative billboards that helps the public “find” those that have gone missing. The advertising campaign cleverly employs polarizing film, along with a billboard that looks like an oversized Facebook Page.
The first step was to set up TV screens without polarizing film on the streets of Hamburg, which through the naked eye appear to be blank. The second billboard, shaped like a Facebook page, had polarizing film stretched across a large window which passersby could see through.
