In stark, bold primary colours - this Father's Day card celebrates the unsung superheroes that don't so much fight the forces of evil as much as lounge in the front room in their boxers - Dads. Clark Kent had his off days too, you know. A royal blue card picturing bright red underpants with the phrase "In my free time I fight bad guys" across the waistband, surrounded by off-centre gold stars. Underneath, an admirable sentiment: "Not all superheroes wear capes"..."Some wear underpants and play xbox on the sofa", in white and gold lettering.
