Hey Hector, it's all custom.
See how the two 'e's are different in 'Nordeste'?

(I mean Helder, of course. Sorry!)

Eduardo, remember there are faces that use alternate characters for the ending of words, this could very well be a typeface. Because it came from Landor Associates, I assumed they had it custom made and charged the client a fortune.

Like Eduardo said, it's custom. Done by Landor.

Doesn't exist anything similar? I knew that landor did it but is it using another type as base? or completely custom? can I find anything similar?

These might be in the ballpark ?

1. Zapfino by Prof. Zapf
2. Scriptina by Apostrophe
3. Phyllis digitized by E+F

Phyllis has the double stems

Chopin has similar delicate flourishes.
