Back in the 1950's when television had little penetration into the homes of Eastern Europe. Vehicle makers would advertise with pin badges that over time became the schoolboy collectable of choice.

Famous Czechoslovak brands such as Jawa motorcycles, Skoda cars and Tatra trucks became internationally famous and a source of pride to the people.
