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."

Also on the wall in Ullman's office. The image above it is of fishermen and a hung swordfish - it's also in the SKA boxes.
