Neutron: ponder your posters
This one promotes a significant Sourcer business you're a fan of. The Uplink corporation is actually Syndicate-aligned, and provides digital anonymization services you use sometimes, though you're not nearly as dedicated as their agents, who command the telecommunications underworld. Some truly classic hacker stuff.
You don't actually know what that one's about. You have a very specific era and category of spacecraft you're focused on, and any of the others is a complete miss. It was really a really nice gesture that WhiteDwarf gave you a poster about some form of then-cutting-edge spacecraft prototype from long ago. It might not invite your focus much, but as a reminder that your team cares, it does warm your heart.
