In the Nevada Museum of Art

I am volunteering today in the Library of the Museum which is mostly a quite lonely job. Not many visitors come to see the books. I take it that all of you know how a modern library looks, so I won't post a picture of the books but rather one that shows a piece of the exhibition by Erika Osborne with the title "The Back of the Map". After my shift I will go over there to get more information about what she wants to express by what she does. For me as a retired geography teacher this looks quite intriguing! - - -

This is what I found on the wall of the museum as an explanation ( and I must say, I found it a little "thin"..):"Maps are not pictures of the land but rather abstractions, we use to understand where we are and how to move across the landscape. Maps can be as complicated and difficult to read as an abstract painting., but because we are sourrounded by maps (....) we are adept at reading them. Our familiarity with them means that we also sometimes forget that they are amazing objects.
In her ongoing series of mapping projects Erika Osborne positions people as they gaze at landscapes such as the Grand Canyon. Then she paints lines from maps representing those scenes on their skin. When we view Osborne's photographs , she asks us to think about the differences and similarities between looking at a place, reading a map, and looking at a picture of a place. ...."
The text further describes other maps that convey different types of information, but never refers to the title of the exhibition nor explains, what the special goal or effect is of painting parts of a map on the back of a person.
I am a little disappointed. Does she want to say: we are part of a map? A place? A picture, always?
