At this point, we could hate on every advertiser that’s trying to co-op the Royal Wedding for their own gain, but this execution from OgilvyAction for Post-It Notes is pretty sweet. All around London, they’re posting these billboards that include the line “May You Stick Together Forever.” Very smart way to link the brand to the event without going all sales-y on the viewers. There are many less tasteful promotions going on, so way to go, Ogilvy and Post-It.
