French-suited Cartes Lenormand published by H. P. Gibson & Sons Ltd, London, printed chromolithographically in Germany by B. Dondorf. The set was probably published in the early 1920s because H. P. Gibson & Sons Ltd didn't exist until 1919 after Harry Gibson sold the International Playing Card Co (formed in 1903) to De la Rue. The retail price was 3/6d per pack.

Above: the back of the cards is the standard Dondorf back design, without any manufacturer's details overprinted. The booklet accompanying the pack states: The Art of Telling Fortunes "Lenormand" as professed by the celebrated Parisian Diviner Sylvia d'Arville - H.P. Gibson & Sons Ltd., London E.C.3. and then goes on to explain that Mlle Sylvia d'Arville is a most celebrated fortune-teller whose grand-mother predicted Napoleon, his greatness and his victories, and his subsequent fall and ruin.
Note: Mary Greer has shown that the earliest forerunner of the Lenormand cards is a 1796 book in English. See her blog: Mary K. Greer's Tarot Blog→
