On 4 November 1932, Mr Adams opened the groundbreaking Black & White 4d milk bar at Martin Place, Sydney - credited by historians Leonard Janiszewski and Effy Alexakis as the world's first establishment dedicated exclusively to milkshakes and cold beverages served at a bar.
Within its first year, the Black & White welcomed 27,000 customers per week, sparking a nationwide movement that saw 4,000 milk bars registered across Australia within five years.
The phenomenon spread globally to New Zealand, South Africa, Great Britain, and Europe.
Mr Adams’ grandson Michael Gerondis is selling the two-bedroom property with his sister and said the building had been in their family since it was built by their grandfather.
“My grandfather arrived in Australia from Greece in the early 1920s at just 14 years old,” Mr Gerondis said.
“He gave the property to my mother as a wedding present, and she owned it until her passing last year.
“My sister and I purchased it from our other siblings and undertook an extensive renovation to honour both the building's heritage and our grandfather's legacy."
