the most famous Apollo Mars Fly-By proposal is from North America Aviation

Douglas proposed MORL Station with Apollo Block III for Mars Fly-By
Technical Proposal for a Study of Spacecraft for Manned Planetary Encounter/Retrieval Missions, SD 67-876, North American Aviation, Inc., Space Division, September 14, 1967.
The apollo mars designs were a study by North American Aviation (they would would'nt they) and if the politcal will had been right they might have come off. But they were doomed as soon as follow on to Apollo was cut.
I believe the artwork illustrated the flyby mission but the apollo csm was fitted with 3 engines from the descent stage of the LM. It could be updated with the Orion CEV!!!
There was an artificial gravity version proposed with the CSM as a counterweight.
