This is an old historic photograph of Chalkhill Estate in its early days, possibly even dating from 1970. The photograph is therefore at least 40 years old and at the time it was taken, it wasn't common for people to own cameras and certainly not many residents of Chalkhill Estate would've owned one, I know this to be true because I have enquired of the many former residents I know and am still in contact with over the past few years about photographic records. This photograph is unique and there would not be many, if any others taken around this time and therefore it has an important and irreplaceable value in supporting this article; it is possible that this photograph is the only one in existence in this form or quality and showing the detail necessary. Furthermore this photograph illustrates the nature of the development and clearly shows the different blocks connected by the short walkways. Former residents of Chalkhill Estate who would view this article, would also recognise the stairwells and lift access shafts - this level of detail could not be relayed by text alone. Another important aspect of this photograph is that it shows the relationship between the blocks of flats (apartments) and the open-spaces, again an illustration or text alone could not do this. — Preceding unsigned comment added by Martynsaxman (talk • contribs) 2012-10-29T12:14:56

Unfree photos of buildings are normally not allowed per WP:NFC#UUI §1: it is possible to replace the photo by going to the building and taking a photo of it. However, the article Chalkhill Estate tells that "The 1900 houses and flats were eventually demolished and Chalkhill Estate was refurbished early 2000." Are the buildings on the photo some of the demolished buildings? It is normally assumed to be impossible to replace a photo of a demolished building unless someone can prove that a freely licensed alternative exists.

The photo is sourced to Middlesex County Press. Press photos are normally unacceptable per WP:NFC#UUI §7, but this page credits the image to some John McCann instead, suggesting that the image comes from an archive. If that is the case, then I suppose that WP:NFC#UUI §7 isn't an issue. --Stefan2 (talk) 15:12, 29 October 2012 (UTC)

This photograph shows buildings that no-longer exist, buildings that were demolished approximately 12 years ago. --MartynSaxman (talk) 14:00, 31 October 2012

I have updated the information page for this image to include a credit to John McCann. --MartynSaxman (talk) 14:23, 31 October 2012

I now have formal permission from Brent Archives ([email protected]) to use this image plus one other I will be uploading. The email I received reads as follows:

Dear Martyn

Sorry for the delay. Our archives department advise as follows.

“I have checked with my colleague and am told that attempts were made to trace this photographer in the past (unsuccessfully), so it would be alright to use on the understanding that every effort has been made. The enquirer should just make sure that Mr McCann is credited as the photographer and that the images were made available to be seen, by Brent Archives”.
