Germano's, the biggest shop in Lajes (second biggest town on Flores - although it's not really a town, just a village) have a good map on their plastic bags:-
Sorry the image is a bit fuzzy but taking a picture of a plastic bag with a flash produces disappointing results.
However, my favourite Flores plastic bag - although it doesn't bear a map - is that of our local shop here in Faja - Jose Antonio Ramos Teodosio - "Big Joe" as we call him. Please note, it's not possible to wheel a trolley round Joe's shop as the bag implies. It's too small. But it has everything you would need on a day to day basis. And the kindness of Joe and Linda is something you don't find in many places.
