I think this is southbound on Spencer St in Melbourne, and now I'm encouraged as I spotted the highway sign, the right shape for "50". Google doesn't have "Street View" for this area, so I can't look for this building. It may well not be there anymore, as I took this photo 35 years ago.
I'm using Picnik to improve some of my old flickr pictures. This was scanned from a fading slide a few years ago. I thought it needed help, and to be seen again! This isn't great, but a lot better than that old slide.
