Poppy Appeal posters defaced by anti-war campaigners
The poster shows Hester Wright and her son Josh, six, holding a portrait of her late husband Private Damian Wright.
Pte Wright, 23, of Mansfield, was killed by a roadside bomb in Afghanistan in 2007.
The Royal British Legion poster bears the slogan 'For their sake, wear a poppy' – but on billboards in Gillingham, Kent, campaigners have changed the wording to read 'For their sake, prosecute Blair'.
Other billboards in the town have also had their slogans changed.
Pte Wright's mother Debbie Smalley, 45, said: "Whoever did it should be ashamed."
A spokesman for the British Legion said: "We do understand that the current campaign in Afghanistan and the recent activities in Iraq are not popular universally in the country.
"Opinion is divided but we do find that the public is four-square behind our British Armed Forces who are out there representing their country and making sacrifices."
He said the vandalised posters would be rectified.
