A great image from the Jim Endruweit archive, captioned by Jim as the 'Indefatigueable Bob Dance (Lotti)'.
The image is from Sebring 1965, where Team Lotus was running the Works Cortinas. Bob on the left, Jim centre and Tony Hegbourne on the right. Jim references Bob's Team Lotus nickname of 'Lotti', which arose from Bob being recognized as the Colotti gearbox specialist. Also Bob was renowned as being tireless, amongst his peers who all worked extraordinarily long hours, both back at base and at the circuit; hence Jim's caption.
