This mural, alongside the remaining bit of the old electric bus turn-around off upper Rosebank Road, is around 20-30 years old, I reckon. I've seen it for years. The back door in the photo on the right leads to what started out as the Avondale Plunket offices from the 1940s when this (the local loos) was built. Plunket moved out in the 1980s, wanting more space. And probably something less drafty -- my mum often told me that the reason why I wasn't a "Plunket baby" in the 1960s was because of one visit she made with me to see the nurse there. Through lack of room, after the check-up and weighing etc, she was asked by the nurse to dress me in the drafty corridor. Mum never went back there with me again.
From the 1980s to sometime in the 1990s, those back rooms served as a base for the Council traffic department, until amalgamation swept that away from 1989. The mural is linked into the traffic safety aspect of the officers' work. The offices are still Council owned, but have been used by various community groups since.
I was asked recently how old the mural is. I'm still scratching my head on that one -- but I think it's done very, very well against the elements, car exhausts from vehicles parked just across the way, and taggers.
