Last, but not least, with a vivid color version of the image and superior caption of:

 

“MEM ascent stage liftoff. The ascent stage was a stage-and-a-half design with a cluster of approximately conical expendable propellant tanks and integral tanks in its cylindrical core feeding a single engine.”

Unfortunately, no signature is visible. A very similar Mars Excursion Module (MEM) depiction, also within NASA’s grand Integrated Program Plan (IPP) is by Renato Moncini. However, its depiction of the Martian landscape doesn’t agree with that of my posted photo, sooo…possibly/probably not by him. ¯\_(ツ)_/¯
