CEREBUS #169 Aardvark-Vanaheim. By Dave Sim and Gerhard. 1993.
There are better pages in this issue but I wanted to post this one as it is the final appearance of Lord Julius. (One of his Like-A-Looks shows up later, but that doesn’t count.) It also gives the clearest explanation of not only how he remains in power, but how he manages to accumulates more power. (He throws money at his enemies and buries them in bureaucracy.)
