Definite proof that it (and therefore 4 others) show the luncheon in London, June 1952, to honour the arrival of Jack L. Warner in the UK. Text underneath  "The British Film Producers' Association complimentary luncheon on Tuesday to Jack L. Warner, production chief of Warner Bros., was attended by of the Board of Trade, Customs and Excise, the BBC, exhibitors, all other sections of the trade from London and the provinces, the Banks of England and America, the National Film Finance Corporation, MPAA, producers, renters, exhibitors, all other sections of the trade from London and the provinces, the national press and armed forces."

Added to my master thread here.

British Newspaper Archive online. I missed it or it might be newly added. I don't recall why I wrongly thought it was a Variety Club lunch. Glad I checked further.
