Pseudo-political buttons featuring NBC TV show characters.

I’m unsure of what year these came out because all six of the series above were in production between the years of 2006 and 2010… though due to there being a presidential election in 2008, that would be the most likely date.
[update] Chris Noth left L&O:CI at the end of the 7th season, August 2008. So that confirms it’d be as late as 2008, though he was gone before the elections happened!
