A man who possessed cartoons showing TV character Bart Simpson performing sexual acts has been jailed at Carlisle Crown Court.
Andrew Smith, 55, was found guilty after a trial of nine charges alleging he was in possession of prohibited images of children.
All of the images were drawings.
The court heard that Smith had downloaded the images and burned them to disc before it was made a crime to do this in 2010.
Police had found them after searching his home in Kendal, Cumbria, for evidence related to a separate matter.
At the trial, Smith had said he had a reason for having the files as he wished to campaign for sexual relations between pre-pubescent children and adults to be legalised.
However, a jury found him guilty on all counts.
Smith was sentenced to nine months imprisonment.
