I know my historic American flags pretty well, and I admit I’d never seen this one, other than on the cover of some editions of Tom Wolfe’s The Right Stuff:

Other than the notation, “Jacket design by Kiyoshi Kanai,” the book jacket has no further info. Was the flag just cooked up by the cover designer? Did NASA ever make use of such a flag? Have any Dopers ever seen one in real life?
