'[Invisible Presence] is a fundamental book for comics scholars, whether or not their research is focused on gender studies. Catriona MacLeod’s detailed analysis of BD, and its male and female authors, is a very valuable source of information especially the vast and varied descriptive level of characters, vignettes, plots and actions. [...] I have to highlight the importance of the vindicating aspect of this volume, namely highlighting the void regarding female characters and female authors that persists in encyclopedic and historiographical volumes on BD; the difficulty of creating genealogy about 20th-century pioneering female authors, and the gaps in the creation of female characters other than by straight white women.'
