Bureau of Standards fire test of steel furniture album
In 1901, Congress founded the National Bureau of Standards, known since 1988 as the National Institute of Standards and Technology. It is a non-regulatory agency within the U.S. Department of Commerce created "to establish an authoritative domestic measurement and standards laboratory." In 1926, the Bureau’s Fire Resistance Division burned down two condemned brick buildings in Washington D.C. to study the results. This action was likely the first full-scale fire test ever conducted. The data gathered during these fires was compared against theoretical time-temperature curves that were used at the time, and was eventually used to create uniform fire resistance standards for buildings. This photograph album with explanatory captions documents "a test made with steel office furniture to obtain information on the intensity and duration of fires in buildings." Images show the aftermath of a fire test in an office with furniture supplied by the National Association of Steel Furniture Manufacturers.

Canada Dry is a brand of soft drinks best known for its ginger ale. Canada Dry had its beginning in Toronto, Canada when John McLaughlin (1865-1914) opened a small carbonated water plant in 1890 to manufacture soda water, which he then sold to drugstores as a mixer for fruit juices and flavored extracts. In 1904, he created Canada Dry Pale Dry Ginger Ale. In 1919, McLaughlin began to ship the product to New York City, and two years later opened the first Canada Dry plant in the United States in Manhattan. In 1923, P.D. Saylor and Associates purchased the company from the McLaughlin family and formed Canada Dry Ginger Ale, Inc. Consumer demand grew and this led to national expansion. Much of its popularity was linked to the fact that it was used as a mixer to mask the taste of home brew during Prohibition. The 1930s saw the introduction of other Canada Dry mixers. Canada Dry expanded worldwide during this period. The album was created as salesman's flip chart for Canada Dry distributors to show retailers. There are images of Canada Dry products (ginger ale, club soda, alcohol mixers), views of bottling plants and the manufacturing process which includes photos of ginger being harvested in Jamaica. Advertising campaigns and point of purchase "sales boosters" are illustrated. Lastly, there are merchants' testimonials and statistical marketing information for retailers.
