Didn't have the opportunity to snag any as a kid, so I've been scouring the internet to try to find any now. Was able to find meet the teams for sniper, demoman, scout, and sniper v spy update poster. My holy grails are definitely medic, pyro (sunset variant), and that black and white Aperture Labs Portal 2 concept art, but I'm interested in seeing what anyone may have lying around that they'd be willing to part with.
