That looks like a very flattering, and somewhat unconventional, official portrait of Julia Gillard:
It does look like a selfie blown up large, though; which I think will make it look out of place with the others. Still, she should be happy with it.
And by the way - she continues to be one of the most dignified and likeable public figures around. History will remember her as a basically good Prime Minster who had the job under very difficult circumstances.
