I think these ones were from a X'mas season made by SIDUL. On the back tells you how to make a wrapping package for sweets.
A sugar maker, SIDUL, has done a series of portuguese traditional costumes from different regions.
On the back of "ALGARVE" one, it has a receip of Dom Rodrigo which is a traditional desert from the region.
Each NICOLA's package tell you the portuguese poplation in a different country.
"Only one portuguese lives in Sudan" apparently...
"Pacote de Açúcar"
On the limited spaces of sugar packages, you see many different designs and sometimes with interesting information.
I'm always looking forward to finding new one.
