This paper addresses the challenging problem of assessing the creativity of visual advertising. Drawing inspiration from marketing research, we decompose the creativity of visual advertising into "unstructuredness" and "originality." Based on fine-grained human annotations on these dimensions, we propose tasks specifically tailored to the subjective issue. We then evaluate how state-of-the-art visual language models (VLMs) perform on the proposed benchmark, demonstrating the potential and limitations of using VLMs for automated creativity assessment.
