Examples of geospatial scientific posters

Most GIS scientific posters will come out of either Universities or State GIS conferences. Here are two examples:

The Ohio GIS Conference has a yearly poster/map gallery that delinates between General, Analytical, and Communicative categories (2010 link).

Brown University

Look on http://wiki.osgeo.org/wiki/FOSS4G_2009_Posters for some examples. Unfortunately, I don't found posters examples for the FOSS4G 2010.
