The really cool-looking image above is the work of an illustrator and artist that was mentioned by the blog Pernambucolismo. The Olinda-born artist goes by the name of Ninhol. You can find more info about him and his work by clicking on his signature below. If you want to see straight up images, his archive is what you want.
From the pages of the Brazilian art magazine Sabiá, I found the following on Ninhol.
