The Notre Dame Undergraduate Women in Business (UWIB) host an annual conference focusing on issues relevant to young women and their careers in business fields. The 2015 conference was about "finding a career you path you love" and held on Valentine's Weekend.
The identity pairs vibrant colors and flowing script type with Archer. The poster and other materials strike a balance between professionalism and the unavoidable imagery of Valentine's Day.
UPDATE: While I was not involved in the process, I have been informed that this look was so popular it was re-purposed for the 2017 conference!
