I read somewhere that Kerouac didn't just start writing his well known works one day out of the blue, but worked long and hard at his craft. 'Atop An Underwood' is good evidence to support that claim. These are the early works of a writer in the making, probably more interesting to anyone seeking background or biographical information, but definitely enlightening to any fans of writing or the writer.
Great collection of Kerouac's early writing!
