Alex Toth was a professional cartoonist who was best known for his designs for Hanna Barbara during the 1960s and 1970s. 'Jonny Quest', 'Super Friends', the original 'Birdman', and especially 'Space Ghost' all show the influence of his style of art. And that style was "re-born" on Adult Swim with the launches of such shows as 'Space Ghost: Coast To Coast', 'Sealab 2021', and 'Harvey Birdman, Attorney At Law'.
Alex Toth died at his drawing table on May 27, 2006, so in a way it could be said that he died with his boots on. The following week, Adult Swim devoted bumps to Toth which simply read "Alex Toth 1928-2006". The words then faded out and the "[adult swim]" logo was not shown. This was a style which the network only used when mourning the passing of someone they deemed to be an important person in their realm of cartoons.
