Japan Railways Poster

Hi,
since 3 days i`m back from my awesome 3-weeks Japan trip.
During my travel i saw a lot JapanRailways Posters in the subway or JR-stations with beautiful Japanese landscapes. We asked at a JR Travel Bureau where we could get or buy these posters, but they didn`t understand our english question I think :)

Please does anybody know where i can get these JR Posters ?

Thanks a lot,
Vivien

You can write to them and ask.

The JR group is devided into several companies depending on the region.

For example, JR East (representing Tokyo area and the Tohoku region) has offices as follows;
