I have advised PROV in the past of incorrectly-captioned photos.
There is an e-mail address on the websitehttp://www.access.prov.vic.gov.au
but I recall that there was a feedback form attached to the photo.
I have never been back to see if the change was made.
In another forum, another of the incorrectly-captioned photos in Prof Lee's book was identified (Spencer St, not Flinders St). I haven't checked, but that could well be another PROV error, not an author error.
On a quick search just now, I couldn't find the photo from this quiz which has triggered this followup.
With the location wrong, there is no guarantee that the date is correct either. However, 1905 doesn't seem to be way out; it could be 1910, probably no newer than 1915 [the main clue is the clothing].
