Quite simple, this week. The theme is avatars of people called David (or Dave, Dafydd, Dawud, etc.) - given name (as they are most familiarly known) or last name are allowed. Real-life examples only, please - no fictional Davids or Daves, so for example you can have David Copperfield the magician but not David Copperfield the Dickensian character. If it's a based-on-real-life character called David being portrayed by an actor, again I won't allow that this time - unless the actor is called David, of course. Some examples here: http://en.wikipedia.org/wiki/David_%28name%29 Entries open until Friday night. Usual avatar restrictions apply.
^^ That gets a vote from me. I'm going for this: Paralympic 4-time gold medallist at London 2012, David Weir.
OK, I don't think hubby would want me to make an avatar of him for this contest, so I'll go with another Dave: Dave Letterman
