Part of the herbarium has been shown in March at Tangent Project-Barcelona, and in October 2020 at the Natural Science Museum-Lisbon. At BienalSur I propose an inhedited integral version, made up of 50 pages of 40x50 cm each - 20 of them are new pages, including the ones realized in site. I suggest to show it up in a wall/30m,or room space/40m2 installing the pages one after the other as a spacial book, or at Museo Argentino de Ciencias Naturales, installing them among the museum collection.
