The Gentlemen in Green... Carter and ???

Fellow Readers,

Once in a Lin Carter story, Carter wrote -

"The Gentlemen in Green... was neatly but cheaply dressed, slim and going
gray over the temples; he wore an old suit of bottle-green corduroy, with a
loose foulard at his throat, half-hidden behind a sharp little spike of a
Napoleon III goatee".

Does this figure and description seem familiar to anyone? Has a similar type
of character appeared elsewhere?

Cheers
