Mike Lane, the former editorial cartoonist for the Baltimore Sun, announced last month that he has retired from editorial cartooning. Lane made the announcement in a letter to Daryl Cagle, whose Cagle Cartoons Syndicate carried his work.
"My quitting editorial cartooning comes because it’s time, not because of my health," wrote Lane. The letter and Cagle's comments can be seen here:
