Just for a lark, here’s the original finding aid:
Description: ARTISST CONCEPT OF UPGRADED CENTAUR Photographer: REQUESTER
That’s not super helpful, and knowing the paining was photographed in 1991 just tells me it’s pre-1992. The dual thrusters made me think of Centaur, and the uncrewed Shuttle-C in the bottom left corner gives some context. Either way, it’s a beautiful image and you didn’t come here for an education, you came here to look at pretty pictures of cool stuff. Right?
So, I think this is a shuttle-launched Centaur upper stage or ‘Shuttle-Centaur’ bound for lunar orbit. If you know otherwise, please do let me know. I read all the comments, and I super promise I won’t be offended.

This is an artist’s conception of the proposed “Power Tower” space station configuration, shown with the Japanese Experiment Module attached. This model and several others were examined before deciding on the Space Station Freedom structure that was later abandoned in favor of the International Space Station.

In this artist’s concept from 1971, an Earth-to orbit fuel tanker approaches the Orbital Propellant Depot. As envisioned by Marshall Space Flight Center Program Devlopment plarners, an orbital modular propellant storage depot, supplied periodically by the Space Shuttle or Earth-to-orbit fuel tankers would be critical in making available large amounts of fuel to various orbital vehicles and spacecraft.
