Conkeror does not yet have an official logo. (It's in progress.) But here are icons and possibly other graphic materials made and shared by community members. Note to package maintainers: do not package the artwork on this page with Conkeror. We are still working on the official logo.
I made this chestnut kind of icon when I couldn't find one on the web. This is after an image i saw on a mailing list. I don't know if it has the right licences.
