Portraits for ministers, spies, gentlemen, generals, leaders etc. Where do I find them?

I really, REALLY love the new style of the portraits for characters

They look like my drawing style, but coloured in (in a way I adore)

In short, I LOVE these portraits, and I want to gaze at them all, but I have no idea where to find them in the files and folders of NTW and Steam

Does anyone know? Thanks

Anyone? (Shameless Bump)
