The ad, created by CHI & Partners, instructs the readers on how to fold the paper to create the illusion of a bouquet of red roses, as modeled in the gallery by Campaign's news editor, Maisie McCabe.
Several supermarkets, including Tesco, Sainsbury's, Waitrose and Morrisons have also taken out tactical press ads to promote their stock of flowers and meal deals to last-minute romantics.
Coppafeel, the breast cancer charity, has placed an ad supported by Saatchi & Saatchi Health and the production studio TaylorJames.com.
The light-hearted ad encourages women to give themselves "some love" on Valentine's Day and promotes the charity's 'BOOBLOVE' text service, which sends reminders to anyone who opts in to check themselves for signs of breast cancer monthly.
McCann Melbourne has created a Valentine-themed follow up to its "dumb ways 2 die" spot for Metro Trains.
