Smarties is that kind of sweet that you can’t help but like - psychedelic coloured chocolates that don’t stain your shirt. But, from a PR point of view, where’s the story?

Smarties have done a great job with a simple idea to launch the fact that blue smarties are back, having been banished a couple of years back for containing artificial colours/flavourings.

Commissioning a food artist to recreate famous faces and landmarks out of Smarties must have taken all of 30 seconds to think of (when in doubt, marry marketing and art, that’ll work!). But Guardian Unlimited likes it enough to feature all the art works on one of its galleries linked from the home page, complete with mentions for the blue smartie comeback.

The Smarties website takes the theme to its natural conclusion with a kids’ food art competition, with winners’ works exhibited at the V&A in London.

As this campaign idea shows - much like Smarties - some oldies are still goodies.
