Do not erase

For a number of weekends now, my son and I have attended several university open days, touring facilities and listening to presentations in lecture theatres up and down the land. These photos of blackboards by Jessica Wynne look quite familiar—and equally incomprehensible.

Wynne tells Colossal that she enjoys photographing the dusty work surfaces because of “their beauty, mystery and the pleasure of creating a permanent document of something that is ephemeral.” The “Do Not Erase” photo series, soon to be published in a book by Princeton University Press for release in 2020, includes boards from institutions and universities around the world. Wynne hopes that viewers can appreciate the aesthetic of the worked surfaces while “simultaneously appreciating that the work on the board represents something much deeper, beyond the surface.”
