As Irini Boudouri has shown, in addition to being an adept craftsman, Boissonnas was a canny businessman, who persuaded the Greek state authorities that his photographs would enhance the country's political, commercial and touristic image abroad. Boissonnas contributed his professional photography, and the services of the family printing firm "Boissonnas SA" that he founded in 1919, to the expansionist ambitions of the Greek state. He had already secured a small grant for the purpose from King
George I in 1907, but gained substantial sponsorship in 1913 for the purpose of photographing and publishing imagery of the newly acquired territories of
Epirus and
Macedonia. He had an exhibition
Visions of Greece in Paris over February–March 1919 of 550 of his photographs, accompanied by a 260-page illustrated volume (published by the family firm), at which Edouard Chapuisat, editor-in-chief of the
Journal de Genève, announced: "Today, all eyes are turned upon Greece, which aspires to regain that place in the East which she occupied so many centuries ago. The support of faithful allies anticipates the hour when Greece, which has given the world the purest jewels of civilisation, will contribute to the reconstruction of Europe on the very borders of the East." the text of which, he reported to the Greek government, "quite apart from the high artistic quality of the illustrations - reaffirms in the most categorical way the legitimacy of [Greek] claims over these contested regions." ''La Campagne d'Epire
and its companion, La Campagne de Macedoine'' published 1920-21 both included his photographs and texts by Fernand Feyler, a retired Swiss colonel and military historian. After the defeat of
Venizelos in the elections of November 1920 and the country's increasing diplomatic isolation after the advance into western Asia Minor the Foreign Ministry's Press Bureau worked to ensure positive coverage in the international press. Frédéric's son Henri-Paul, with Feyler, were contracted to cover the campaign; Henri-Paul would provide the Greek government with photographs, as well as placing some in the Swiss press, while Feyler undertook to publish articles in the
Journal de Genève and also to publish a book about the campaign and on 'the rights of Hellenism in Asia Minor'. Henri-Paul placed at least 800 photos with the international press, and the Greek ministry paid the newspapers
Le Matin,
Le Journal, ''
L'Écho de Paris and Le Petit Parisien'' 100,000 francs each during the course of 1921, committing the newspapers to "refrain from publishing anything which would adversely affect our interests [ ... ] and furthermore, to publish the reports and bulletins with which we will supply them." == Egypt ==
