The last thing you want to do in Chicago is cross City Hall.
But a local mapmaker says he's fed up and preparing to sue Mayor Rahm Emanuel's government after the city allegedly "stole" his maps nearly a decade ago and has refused to pay him royalties.
Christopher Devane, founder of Big Stick/Neighborhood Ties, told FoxNews.com that the city repeatedly has rebuffed his appeals. Though maps might seem a matter of public domain at first blush, Devane claims that the city -- and subsequently other companies -- have gradually plucked away at his work.
"They just refuse to acknowledge the fact that they plagiarized my map," he said.
A cursory glance at the map Devane produced and the map used on the city's Geographic Information Systems website shows striking similarities. Though the color scheme and design is different, each map contains similar neighborhood boundaries and labels.
