This is a hard to find two deck set of KEM Stratosphere playing cards.  Only made for a few years, these 1940 Stratosphere cards were designed by Richard Loewy, "the father of industrial design."  

from Wikipedia:

Raymond Loewy was a French-born American industrial designer who achieved fame for the magnitude of his design efforts across a variety of industries. He was recognized for this by Time magazine and featured on its cover on October 31, 1949.^[3]

He spent most of his professional career in the United States, becoming a naturalized citizen in 1938. Among his designs were the Shell, Exxon, TWA and the former BP logos, the Greyhound Scenicruiser bus, Coca-Cola vending machines, the Lucky Strike package, Coldspot refrigerators, the Studebaker Avanti and Champion, and the Air Force One livery. He was involved with numerous railroad designs, including the Pennsylvania Railroad GG1 and S-1 locomotives, the color scheme and Eagle motif for the first streamliners of the Missouri Pacific Railroad and a number of lesser known color scheme and car interior designs for other railroads. His career spanned seven decades.

The press referred to Raymond Loewy as The Man Who Shaped America, The Father of Streamlining and The Father of Industrial Design.^[2]
