I've posted a Zippy postcard before (see here); the Mystery Sender is fond of Zippy, too, and has sent a couple Zippy cards in the past. This Zippy card comes from my friend Steve, who sends me packets of cards when he's cleaning out his office, or attending a book or comic/cartoon trade show.
Something about this card cracks me up. Perhaps it's the headline, perhaps it's the random mention of Belgium. It could even be the subtle nod to the surrealist artist Dali, with the melting clock on Zippy's shoulder.
