The Inventions & Discoveries card series was released in 1960 by Sunblest Tea. Each card measures approximately 1.375 x 2.625 inches. The 50-card collection showcases inventors and scientific discoveries of the 19th and 20th centuries. The cards were distributed in two 25-card series with boxes of Sunblest Tea. A collector album was sold separately for six pence.

Wernher von Braun and the V-2 missile are featured on card #47, "Rockets Into Space." The Vergeltungswaffe 2 (Retaliation Weapon 2), officially designated as Aggregat 4 (A-4), was developed under the direction of von Braun at the Peenemünde Army Research Center in Germany. On June 20, 1944, A-4 MW 18014 became the first object launched into space, reaching an apogee of 109 miles (176 km).

The card image is based on a photograph of Project Hermes V-2 No. 54 at White Sands Proving Ground on January 18, 1951. The Naval Research Laboratory sounding rocket carried an experiment package to measure cosmic and solar radiation. The liquid oxygen flow failed at an altitude of about one mile (1.6 km) . General Electric constructed a total of 67 rockets from captured German V-2 components. Project Hermes conducted V-2 tests from March 15, 1946, to June 30, 1951.
