The poster shows widow Hester Wright, 22, and her son Josh.
Josh is holding a portrait of his dead soldier dad.
The poster originally read: "For their sake, wear a poppy".
Someone changed one version of it outside Gillingham railway station, in Kent, in England.
A number of other Poppy Appeal posters have been changed to make the original message read "For their sake, bring them home". (Poppy Poster 1)
