The name of a slain Charlie Hebdo cartoonist was misspelt on a commemorative plaque unveiled a year after the terror attack on the Paris satirical magazine.

The plaque was unveiled by President Francois Hollande on Tuesday, January 5, outside the former offices of the magazine in Rue Nicolas Appert.

The relatives, dignitaries and journalists assembled for the ceremony soon noticed an error in the 11 names of victims inscribed on the plaque, with the surname of cartoonist Georges Wolinski mistakenly spelt 'Wolinsky'.

Wolinski was one of the magazine's best-known cartoonists, signing his cartoons with his surname instead of the nicknames used by others, and serving as the magazine's editor-in-chief between 1971 and 1980.

The plaque was soon hidden again, and the etching company blamed for the error said it will correct the plaque within 48 hours.

The magazine has just released the cover of the edition marking the anniversary of the attack. It features a bearded man representing God, with a Kalashnikov slung over his shoulder and the headline 'One year on: the assassin is still out there."
