In 2018, birthday were asked by product and exhibition design studio 24 Design to create the branding and promotional materials for the The Exechequer and Bishop Cosin’s Library in Durham.

The approach was to draw influence from the mark of the Bishop of Durham, John Cosin, which adorned the facade of the library.

A humanist font was chosen for it’s hand-written features, as many of the books in the collection feature this style.
