Per second-hand information from a reputable source, fireman Eldon Morgan of the D&RGW presumably witnessed Festus J. ('Jim') Shaughnessy-Frothjaw apparently steering with his knees while holding his large camera out of the window of his car with both hands to capture wind-deflector-equipped #487 running so fast from Alamosa toward Antonito that the lettering on her tender was swept into a reverse of the normal forward slant:
Per said reputable source, that's Eldon in the gangway leaning on his shovel as Festus risks a lifetime of incarceration to capture the scene . . .
