posterity

2003
This review may contain spoilers. I can handle the truth.
The Bill Dunbar character has a Jack Kerouac poster in his home. This scene takes place in 1953. Jack Kerouac did not achieve fame until after the publishing of On the Road (1957). In 1953, Kerouac would have only published his debut The Town and the City, a novel that had somewhat of a 'blink and you'll miss it' reception. No one in America would have had a Jack Kerouac poster in 1953.
I clocked this goof immediately :(
