The cornflakes box will be located at JCDecaux’s Torch site along the M4, for three weeks.
Kellogg’s branded wraparound coincides with JCDecaux’s decision to upgrade the outdoor site to a digital screen.
The outdoor activity complements a current television campaign and outdoor campaign including rail and roadside ads, planned by Carat and booked by Posterscope.
JCDecaux says the site sits on the busiest stretch of the M4 between London and Heathrow Airport and provides 1.8 million views each week.
A Kellogg’s spokesperson says: “The M4 torch provides a unique opportunity for Kellogg’s Corn Flakes to remind people about the best way to start each day.”
