If that 2009 buyer is aware...he might be 
there is a lot for poster collectors in general to cry about as concerns values Jeff.
facts are that the poster market - except for the rarities - is in something of a freefall, affected negatively by being a small market & having far too many posters unloaded via low value auctions.
You can't even just point to the older stuff diving anymore either as modern age posters are falling in values also in many areas because of the sheer quantity being pushed out into the market although there is also a considerable effect due to most of the poster biz now taking place by mail order as almost all movie poster stores - or comic book stores that also sold movie posters - evaporating.
The costs of shipping directly affect final values as do other costs, though shipping costs wouldn't have anything to do with expensive material, but the sub-$50 material is being destroyed by the communal affect of the factors.
the more expensive material is being exposed however for the size of the market and how when each buyer gets "their copy" how successive copies follow a downward trajectory as the market decreases with each collection that removes the poster from their personal list.
but it isn't just posters. Comic books and all other hobbies are suffering in the same fashion, though in comic books, the top of the market is bucking the trend.
