Commander Mark had big bright eyes and a wide mustachioed smile big enough to match his magnetic persona. He wore bright red military coveralls with a bandoleer filled with — not bullets, but magic markers.
His catchphrase was "Dream it. Draw it. Do it." Back in the 1980s and early '90s, millions of children tuned in to PBS to watch Commander Mark create magical worlds with his pen, teaching them how to draw along the way.
