Anything startup relevant would be great. If somebody has done something custom, please do share, I know Dwolla has really cool ones done.
Personally, I have Joey Roth's Hustler poster above my desk - http://joeyroth.com/poster2/
I also built a screenprint station in hopes of making a few more prints. Motivation comes from all the broken/failed prototypes laying about, not so much by witty sayings on paper.

I got a wide column terminal printer in storage, one day I may get it going and print out some others.
Other than that some old movie reproduction posters (Forbidden Planet, Flash Gordon), a few abacuses, some old posters of events I had put on, and other classic computing ephemera.
If you're interested in any of them I could probably have them shipped to you since my printing partner are located in the states. E-mail in profile..
