Context paragraphs:
The Fair Store: The Fair Store was a discount department store founded in 1874 in Chicago, Illinois.  Founder Ernst J.

Lehmann bought and sold goods on a cash-only basis; he offered odd prices (i. e., prices not in multiples of five cents) to save customers a few pennies on every purchase.  The flagship store was moved to the corner of State and Adams Streets in 1875; a modern twelve-story building for the store would be completed on that site in 1897.
