Why is president Gorbachev on pinball machine?

President Mikhail Gorbachev appears on some pinball machines as a symbol of the significant political changes in the late 20th century, particularly the end of the Cold War and the dissolution of the Soviet Union. His policies of glasnost (openness) and perestroika (restructuring) were pivotal in transforming Eastern Europe and improving relations with the West. The inclusion of his image in pop culture, including pinball machines, reflects his iconic status during this transformative period in history.
