I only include it because The Secret Bride (1934) was mentioned recently in the comments section, while on the back of this card it refers to Barbara Stanwyck & Warren William in Concealment. Same movie.
Looking up The Secret Bride on the IMDb, it has some alternate titles, including English alternates His Secret Bride and Concealment. His, is listed as the U.S. working title, to be replaced by The, Concealment is listed as an undefined alternate title — since this tobacco card was issued by Gallaher out of London, I’d guess it was the working title over there.
Text from the back of the card gives us a brief summary of the film:
In this story of political intrigue Barbara Stanwyck features as Ruth Vincent, who is secretly married to Robert Sheldon, the Attorney-General, played by Warren William. They become unwittingly involved in a plot to prove Ruth’s father, the Governor, guilty of bribery. After many exciting incidents he is proved innocent, but the secrecy of the marriage has to be revealed. The cleverly constructed story provides excellent material for the dramatic ability of these two stars.
