Graham was responsible for dressing Queensland's most fashionable set of socialites, models and the state's most stylish from his salon in Brisbane Arcade which first opened in 1963.
The 14-strong collection surfaced as Greenslopes vintage store 'Can You Keep a Secret' received the pieces from the family of Graham's former personal assistant, the late Mrs. Vilma Parker.
Brisbane Arcade Marketing Manager Rachel Pearson said the unveiling of the collection will fit perfectly with the upcoming anniversary celebrations and is an incredible coup.
"Our research and discussions with Queensland Museum conservators has revealed that Harvey Graham was most certainly a trail blazing fashion force and an important part in the history of Brisbane Arcade being so synonymous with fashion," she said.
Thee frocks will be displayed as part of the Arcade's 90th anniversary celebrations upon beehive-topped 60's styled m odels.
Graham's pieces will join the likes of Bora, The Hat Box, Darb Bridal Couture and Pia Du Pradal during the festivities happening from October 12 to 19.
