Many thanks Frank
Charlotte mentions this
photographers can come out of the woodwork
That was a very helpful post in light of this - I will endeavour to find out the photographers names - I think a fair few from the 40s and 50s are no longer with us, but there is always there family - if mentioned in the magazine I will try and contact them. After every attempt with no response I will indeed write on image
'Copyright (unknown or name) attempted to trace, please contact if you know them' - that is an excellent way of expressing it.
I won't post any more magazine images until further investigation.
I hope I can find an easy route for getting in touch with photographers of the images - the magazines sometimes give the photographer, the Studio Year Books do not - I will just have to write to various authorities as above and ask if they have information - then after a period of time post with above statement.
I guess this goes for all images from the time frame I am talking about regardless of the publications demise?
