From the Time and Mediaite article Chris posted, it looks like Sanders and/or his campaign staff have represented the pic as having Sanders in it. And Sanders had an opportunity, through a Rachel Madcow debate question, to set the record straight but responded equivocally.
So looks like the answer to bn's question is basically, yes, Sanders and his campaign have represented the man in the pic holding the book as The Bern. And it looks like they are being untruthful, perhaps knowingly.
Since this is the same DU-crowd who to this day insist that Bush lied about his TANG service, surely The Bern being caught in a falsehood will turn all DU-folk against The Bern and to Tsaritsa CHILL! Right?!
