Oh, ech... just reviewed the listing, there is no pinball art in there. That is a major interest for me... doesn't reduce it enough to bail, though. He also says in one place that there are no multigame art pieces in there but lists them anyway in the breakdowns.
There is definitely a LOT of bloat in there...

That's just SOME of the gigantic stuff that could be chopped down as suggested. So really, if we cut out the less desirable bloat, but keep the source material for the actual classics, we could still cut this sucker down but a strong double digit percentage and not lose a ton of usable classic source.
I would definitely suggest we take a close look at the Star Wars art as part of our evaluation. Looks like there is a LOT in there and that is some of the largest value in the lot.
