Canada's most celebrated and controversial political cartoonist, Terry Mosher, also known as Aislin, has released Oh,Oh, a book which features some of his greatest work.

"It's a collection of what I consider to be my best cartoons from the last three years. Over 200 cartoons, mainly in colour," Mosher told Canada AM.

Oh,Oh is Aislin's 36th book and tackles events from Sept. 11, 2001 to Canada's federal election of 2004.

The nationally-syndicated artist, who borrowed the pen name, Aislin, from his eldest daughter, is recognized for his satirical depiction of prominent political figures and headline-making news.

"It's nothing personal. It's out there. You have all of these wonderful scenarios happening on the public playing field," Mosher said.

"It's my job to comment on it and sometimes take a stance on whatever it happens to be. The whole idea is to create conversation and create interest."

From Martha Stewart and George Bush to the Liberal Party and Canada's involvement in Afghanistan, Mosher's biting caricatures of newsmakers have often elicited both contempt and admiration from readers.

Toronto Star journalist Jesse Campbell once said about Mosher: "Far from losing his rapier touch, Aislin seems to have actually sharpened his fangs with the onset of maturity. He's as merciless as ever."

Meanwhile, a Montreal Gazette reader wrote: "You do wonderful cartoons. Your drawings are superb, and your sense of humour is good too. It's just your mind that worries me."

Despite Mosher's strong editorial slants, he believes in depicting his subjects in the way the public sees them.

"You can't go into an immediate devastating caricature of an individual. You've got to evolve with the public perception of the individual."
