i noticed we have very few pictures on all the groups related to cani stuff that have more than the victim and one or two people in the picture is this because people imagine one person would be a one or two people type meal or some other reason, i can imagine a big party with people being dinner for a lot of people.

The great artist Dolcett created many pictures of modern-day parties or clubs where there were one (sometimes 2) person cooked and a whole bunch of people partaking in the feast.

I have to admit that eating someone is a pretty solitary occupation. Not many people I know would eat someone.......
