American Pepsin Gum Company provided a give-away button that was part of a collectible set. Many gum manufactures in the late 1800s used pepsin powder in their chewing gum and marketed it as a way to aid indigestion. Pepsin was thought to settle stomach issues and help people with digestive concerns. Pink Carnations are sometimes believed to be a symbol of a woman/mother's pure love.

The tulip is a classic flower that has been in cultivation since the 13th century.  In the 1600's, the tulip's popularity flourished when Turkish traders introduced the flower to the Dutch.  In the 17th century, tulip bulbs were commonly traded as currency. Though the tulip is sometimes seen as a flower of love, the Victorians recognized the tulip as a symbol of charity.

The violets seen here allude to Christian symbolism, which are said to embody the humility and modesty of Mary. Other Christian illustrations for the violet represent spiritual wisdom and faithfulness, as seen in this particular button.

The Whittelsey Avian was a U.S. model of the Avro Avian plane manufactured in England. Australian pilot Bert Hinkler used a Whittelsey Avian to complete the first solo flight from England to Australia in February 1928, setting a record of 15 1/2 days.

The Vultee V-1A, a single-engine passenger plane designed by Gerard Vultee, first flew in 1933. Though airlines bought the model, its use was greatly reduced in 1936 when the U.S. government ruled that all commercial passenger aircraft had to have multiple engines. Several private companies and pilots continued to use the plane.

In 1936, Harry Richman and Dick Merrill bought a V-1A for a planned roundtrip flight from New York to London. They had it filled with thousands of ping-pong balls to help it float in case of a water landing. They landed in Wales, went on to London, and on the return flight had to make an emergency landing in Newfoundland before flying on to New York a week later.

Curtiss based their R3C and R3C-2 models on the U.S. Navy's F3C fighter. In the 1920s, the U.S. Navy and Army acquired planes from the Curtiss Aeroplane and Motor Company specifically to race against civilian planes in national and international air races. One of the most noted was the Schneider Trophy, an international competition.

Pilot Glenn L. Martin started his first aircraft company in 1912. It merged with the Wright Company in 1916, but Martin left to form a new company in 1917. The Glenn L. Martin Company made several models of bomber for the U.S. military, including the B-10, B-12, and JRM Mars. The B-10, which went into service in 1934, was noted for its innovations such as rotating gun turrets, enclosed cockpit, and retractable landing gear. The JRM Mars was a type of "flying boat" bomber built for the U.S. Navy that was modified and used as a transport plane during World War II. Martin merged with American-Marietta in 1961 and with Lockheed Corporation in 1995. It is now part of Lockheed-Martin, an aerospace and defense contractor.

The Condor II biplane was a Curtiss-Wright model designed for varied transport. "155" may refer to its cruising speed. Models of the Condor II biplane include BT-32 (for bomber transport), AT-32 (air transport), and CT-32 (cargo transport). Some models of the Condor II offered convertible sleeping compartments and were used by the forerunners of both American Airlines and Eastern Airlines. Condor II aircraft were also part of some civilian and military fleets in the United Kingdom and China. Admiral Richard E. Byrd used a specially equipped model in his 1933 Antarctic expedition.

After President Franklin D. Roosevelt announced in 1934 that the Army Air Corps would take over airmail contracts, Eddie Rickenbacker flew the only DC-1 ever built from Los Angeles to New York to show that commercial airlines were qualified to carry the mail. The flight time of 12 hours, 3 minutes and 50 seconds set a transcontinental record for commercial aircraft. Rickenbacker was the top U.S. flying ace in World War I, with 26 victories. He received numerous awards, including the U.S. Medal of Honor and France's Croix de Guerre.

In the early 1930s, Boeing Company developed bomber aircraft from its existing mail-plane designs. The YB-9 and Y1B-9 were the first all-metal single-wing planes developed for the U.S. Army Air Corps. They featured open cockpits for the pilot and co-pilot, who doubled as the bombardier. Five Y1B-9A test planes were built and entered service in 1932. The more advanced Martin B-10 bomber prototype had already been flown, however, and the last of the Y1B-9As were phased out in 1935.

Boeing developed more advanced bombers such as the four-engine B-17 Flying Fortress and B-29 Superfortress used during World War II. In March 1944, Boeing workers were building 350 planes per month for the war. After the war, Boeing transitioned to building passenger aircraft, including the 747 (1970), 777 (1994), and 787 Dreamliner (2009).
