Set of World Expo '88 Brisbane Souvenir Coasters

This is a collection of vintage souvenir drink coasters produced for World Expo '88, which was held in Brisbane, Australia. The set consists of at least nine square-shaped coasters featuring rounded corners. Each coaster is constructed with a white-faced hardboard top and a cork-derived or similar composite backing, typical of Australian coasters from the late 1980s. The surface features the official 'Australia Expo 88' logo in a bold, multi-colored graphic style including red, yellow, green, and blue. The design includes the event title across the top in a black banner and a large, stylized '88' in a muted, textured gray watermark-style finish in the lower center. A series of vertical graphic lines descends from the letter 'O' in 'EXPO', representing the sun-rays of the official logo. In terms of condition, the coasters show varying degrees of age-related wear; several exhibit light yellowish staining or foxing on the white surface, and there is minor abrasions along the darkened edges. These items are iconic pieces of late-20th-century Australian memorabilia, reflecting the graphic design trends and cultural significance of the Bicentennial year celebrations.
