Summer sports...

I dig holes in the sand.
Tomorrow I'm taking off the umbrella...
      This was a try at ClubMed. I thought creating a specific brand of postcards for them would be a good idea, but they never responded...
The comment is a quote from an advert that was highly successful at the time. A beach girl in skimpy outfit said on huge placards all across France: "Tomorrow I'm taking off the top." And the next week you saw the same girl without a bra, and she was absolutely lovely, and she promised: "Tomorrow, I'm taking off the bottom." And she did, the next week she was stark naked, except she was turning her superb backside to the ogling crowds. And the catchphrase went: "Blahblah, the adman who keeps his promises."
