No worries.
If you're convinced that digital downloads will result in little or no revenue, and I would honestly tend to agree you on this, then I would suggest Amtrak
avoid that route and try to generate at least a
little revenue out of a hard copy version. Passenger rail is already under pressure from so many angles (anti-rail congressmen & governors, freight railroads, accident prone trucking companies, Fox News & AM radio, roadway construction companies, insufficient maintenance schedules, ever larger passenger airlines, Tea Party types, etc.) that any new PR endeavor will need to show some sort of ROI.
To be fair, Amtrak
does give away posters from time to time. They typically wait until there is a specific event or occasion to do so but it does happen. Amtrak also has provided free images capable of being downloaded and printed from time to time as well, although not at 8MP in my experience. Amtrak does not provide prints or high resolution downloads of their most desired poster series and it seems doubtful to me that this is simply a chance situation. I would imagine this is due to some contractual obligation they have agreed to at some point. That obligation
might be possible to renegotiate
if a fee of sufficient amount was charged and split with those who hold ownership of the copyright.
If simply given away as a digital freebie to any who care to download I don't think it would be as easy to get approval from all interested parties. If it was I think we'd already have seen something released long ago. This isn't a huge deal to me, but if and when these posters become available for a more reasonable sum I'd be happy to pick them up and provide Amtrak a little "free" press along with some ancillary revenue in the process. Maybe we should reach out to the artist and see if he's willing to cut us a deal for a lower-quality print at a substantially reduced "AU Membership" price? It's quite clear he has the legal and technical ability to sell these posters, so has anyone ever asked?
