Brasilian reggae/rocksteady blog and sound system crew
You And Me On A Jamboree have an excellent tribute post (in Portugese)
honoring Jamaican folk artist and 80s album-cover illustrator Wilfred Limonious.
Roots-Archives has a fairly good
list of Limonious' album covers. There has been a good amount of
discussion of Limonious' work online, and a few spots to see more of his
work. But alas, the definitive book on this Jamaican original has yet to be written!
