The poster for the Laboratory of Political Urbanism was A2 size, but most of them were digitally printed (photocopies) in two A3 pages and sticked together.
In some of them we add a colour sticker with some extra info, like date of a lecture, workshop, etc.

This poster among other visual stuff I developed for LUP, was selected and exhibited at the II Iberoamerican Design Biennale held in Madrid 2010. (picture at the bottom)
