Often when researching Precious images for the series in Rewind I come across lots of pictures of projection rooms that have no indication of their location and so I do not use them. Consequently, we now have this section on the website where many of these ‘lost boxes’ will be reproduced. If you do recognise any then please let us know so we can correctly catalogue them in the archive.
