I found it, my old notebook. I worked then in the "Palácio Foz" photographic archive. Here are some of the pictures I found there: Ambassador Sir Walford Selby, Ambassador Baron Oswald von Hoyningen-Huene, Joseph Kennedy, Ambassador Sir Samuel Hoare, Ambassador Sir Ronald Campbell,Colonel Donovan, Capt. Agostinho Lourenço, and... I believe Juan Pujol Garcia: his picture, if I may assume it was him, was taken in 1940, during a visit of some "journalists" to "O Século" newspaper.
