What is "hudson's"

Hudson's, or The J.L. Hudson Company, was a retail department store chain based in Detroit, Michigan. Hudson's flagship store, on Woodward Avenue in downtown Detroit (demolished October 24, 1998), was the tallest department store in the world as of 1961, and, at one time, claimed to be the second largest department store (next to Macy's) in the United States, in terms of square footage.
