Expo

The 'Expo' pinball machine, released by D. Gottlieb & Co. in 1967, emerged during a significant period in pinball history when electro-mechanical games were reaching their technological peak. The machine likely drew inspiration from and capitalized on the excitement surrounding Expo 67, the International and Universal Exposition held in Montreal, Canada - one of the most successful World's Fairs of the 20th century.

As an electro-mechanical pinball machine of its era, Expo would have featured the classic mechanical components including relay-based scoring, chimes for sound effects, and vibrant artwork celebrating the themes of world exhibitions and technological progress. The playfield likely included standard features of the time such as pop bumpers, slingshots, and various scoring targets, all operating through an intricate system of switches and relays.

While specific production numbers are not readily available, Gottlieb was the dominant manufacturer of the era, known for producing reliable and entertaining games that were popular in arcades and entertainment venues across America. The theme of international exhibitions and world's fairs was particularly relevant during the 1960s, as these events represented optimism about the future and technological advancement.
