Dutch tattooist Henk Schiffmacher – who decorated several body parts of Kurt Cobain and the Chili Peppers – is doing a joint promotion with the Belgium beer brand Palm. He tattooed a can of Palm and calls upon the crowd to do the same – possible with any sharp object. Photos of the beer cans are to be uploaded on a dedicated Facebook page and the winning can will be produced and displayed in every supermarket in the Netherlands. We wonder whether Palm is your typical tattoo lovers beer – especially when watching the two Belgium, tattoo-less characters trying to sell this promotion – but other than that, we think it’s a good example of how crowd sourcing can work – the task is not too simple, not too difficult, and the reward is attractive enough to be able to incentivize the campaign.
