I am doing some work on a photograph which was taken by this agency.
I think it was run by Charles Henry Park, who worked from 89 Fleet Street.
He is listed in the Newspaper Press Directory and Advertisers Guide 1917 with this entry: “Park’s Press Photographic Agency, Limited. Topical photographs from all parts of the world and news stories will illustrations. Advertising and commercial photography a speciality. Address – 89 Fleet Street, London E. C. Telephone Holborn 2019” http://www.mocavo.co.uk/The-Newspaper-Press-Directory-and-Advertisers-Guide-1917-Volume-1917/409196/295
Do you know anything else about him? In particular the date of his death.
The PPHP has no info on record for this agency, if you do please send answers on an email please firstname.lastname@example.org or call 07802437827
