They're gaining good company with the Duke.
I'd love to see Jimmy Stewart on a stamp, too. Not in one of his Holywood roles, but rather in the Army Air Force officer's cap he wore as a combat pilot in the ETO during WWII. I love his movie roles, but above all I respect his service.
Duke, Jimmy, Bogie... you're sorely missed. At least you're where you don't have to see what passes for "entertainment" these days.
Glenn Miller would be another good choice.
