Purchased in 2009 shortly after the series ended the voting ballots from S02E19/E20 Lay Down Your Burdens have remained in the envelope they were delivered in.
Yet, for the second time this year I have pulled it out to look at it. Once for when I completed my BSG rewatch and the other to show a friend this collectable after he watched that episode. My plan is to put the ballot in a double sided display case but over a decade on and that hasn't happened yet.
