It's been done

Mike Moore opened his piece on a return to Muldoonism this morning with the following:

n the 1980s, a cruelly funny cartoon appeared of David Lange. It had four panels - the first displayed a smiling picture of David, then slowly, over the next two panels, David's face morphed into a picture of Roger Douglas.

I'm expecting a cartoon of Helen Clark to appear, morphing into an angry Robert Muldoon.

It's been done - by Bromhead, IIRC, and quite some time ago. Unfortunately I haven't been able to find an online copy.
