It seems to me like a fair price. I've seen VG-FN condition rolled examples of this poster go for $300-400ish on EMP. But this one is folded and looks to be in rougher shape. Looks like some possible tears, fold wear, pin holes, etc.. Since the single picture is very small, it's hard to make a good condition grade, so I imagine many people were hesitant.
Also, the last three similar (G-VG Folded) examples on EMP went for $86-$111, so the selling price here (plus $25 S/H) seems to be right in the ballpark.
