Teaching the Teachers is a law librarian conference held by Penn State. From the website:
"The Teaching the Teachers Conference provides a foundation in evidence-based instructional design, teaching techniques, and assessment for law librarians by law librarians. The conference was originally dreamt up by Penn State law librarians Laura Ax-Fultz (Dickinson Law) and Rebecca Mattson (Penn State Law) and brought to fruition by an amazing team of law librarians."
I love alliteration, so the conference name speaks to me. The design is meant to be three smaller Ts creating a larger one via negative space. For the banner it was requested to make the main T not-so-negative space.
