The photos in the article appear to be of legit notes, as I searched for the word "Angola" without success (they were able to explain away the fraud to the printer by pointing this out).
According to Wikipedia[1], "Angola" was (allegedly) to be printed on the notes later:
> [T]he contract had specified that the word "Angola" would be overprinted on the new notes when they reached Lisbon and before transport to Angola (they were allegedly for colonial circulation only)
The article has an image[2] taken at the British Museum showing a real and counterfeit note, both with the same serial number.
