There seems to be a movement in design towards more hand illustrated lines rather than bold computer generated patterns and large cut out stencils. Personally, I like both, but it is refreshing to see work that has been hand drawn. The style ranges from lines that are tight and mechanical, to loose and reminiscent of blind contour drawings (I love doing those!).
Here are the old and new (relatively) incarnations of this style in cover art. Beatles’ 1966 “Revolver” and Jet’s 2003 “Get Born”. So everything old is new again, but you knew that, and both CD’s are worth checking out for the music AND the cover art.
