Jewel Tea Company, as it was known from its 1899 founding until the 1960's, was strictly a door-to-door home shopping service for the first thirty years of its existence. In 1932, the company purchased all of the Chicago area grocery stores from Loblaw Groceterias, firmly establishing Jewel in the retail store business as well. To use modern terms, we would call it "adding a brick-and-mortar sales channel". The above photo is circa 1935 and is typical of Jewel Food Stores from the first 15 years or so of the division's existence.
An interesting thing you'll notice if you take a close look at the store's door signs ("Loblaw Out, Jewel In") -seems like they wanted to make sure customers got the message!
