What Blair has, as seen in that first sketch, is one angry (left) eye and one smiley, twinkly (right) eye. Once I'd established that, everything else fell into place. Big ears, loadsa teeth, weak chin, projecting lower lip, conical head and weird top knot (a small echo of Thatcher's resplendent quiff). At last I had a formula that I could use in the strip, with the added bonus that, because Blair's features are distinctive, they could be applied to any object or animal existing or yet to be discovered.
Since then, only details have changed. He's aged, his hair has greyed and thinned, his widow's peak has become more pronounced and the eye has definitely got madder. The other eye has gone a bit wild as well. It's as if the eyeballs can no longer make up their mind. His expanding forehead bears the vivid imprint of the ravages of power.
