Context paragraphs:
Rosa Food: Rosa Food Products was started in Philadelphia in the year 1900 by Giacomo Foti.  He named his store and products Rosa after his wife.  At first it was only a small store at on the corner of 13th and Federal Streets in Philadelphia.  Over time, hundreds of stores bearing the Rosa name were created.  A warehouse was needed to supply all the stores with hundreds of products bearing the Rosa name.  Giacomo Foti and his son, Leonardo, were packaging cooking oils for their Rosa brand, Rita brand and also for private label customers.  As the large supermarkets came into existence, the smaller stores began to close.  It was easier to supply the supermarkets with products than their own stores.  Rosa Food Products then became a wholesale food distributor.

Jones Cash Store: The Jones Cash Store was a mail order catalog business established by Portland, Oregon, entrepreneur Henry J. Ottenheimer in 1882, and is a building listed on the National Register of Historic Places.  Before moving to a larger, more prominent location, the Jones Cash Store operated out of a building at 80 and 82 Front Street in the downtown area of Portland.  As popularity of the mail order catalog grew throughout the Pacific Northwest, Henry sought to find a larger building within which to operate.  He later purchased the property at 111 SE Belmont Street and began construction on his state-of-the-art 80000 sqft catalog supply store.  Because of its location by the railroad tracks and the river, the store could easily ship and receive goods by railroad, steamer ship, and via truck.  The building remained the Jones Cash Store until 1929 at which time it was sold to Montgomery Ward.

Belk Hudson Lofts: Belk Hudson Lofts (also known as Fowler's Department Store or the Lowe-Kilgore Building) is an apartment building in Huntsville, Alabama.  Originally two buildings, the first was built on the corner of Washington Street and Holmes Avenue in 1930 to house Fowler's Department Store, one of several department stores on Washington Street (including Dunnavant's and Kress).  The second building, adjacent to the first along Holmes, was constructed in 1936 as a farm supply store.  Fowler's went bankrupt in 1938, and Belk Husdon purchased the corner building in 1940.  Beginning in 1944, they also leased the Holmes building, and the two were joined.  After Belk Husdon left the downtown area, the building was renovated into offices in the 1980s.  The one-story Holmes building was occupied by Olde Towne Brewing Company from 2004 until 2007, when the building was destroyed by fire.  In the 2010s, the corner building was reconstructed into a loft apartment building, with the original façade kept largely intact.
