In April, Ramsey drew a heartwarming cartoon of Barbara Bush being reunited in heaven with Robin.
"Not every cartoon I drew about President Bush was flattering," Ramsey tweeted. "But the last one is. My prayers are with his friends and family tonight. And the nation. He lived a fascinating life of service."
Ramsey also tweeted a photo of himself in the cockpit of a TBM Avenger.
Ramsey was not the only cartoonist with a heavenly touch.
Gary Varvel of the Indianapolis Star drew a cartoon showing George H.W. Bush holding Robin while putting his arm around Barbara in an illustration titled "The Bush Reunion."
