Primary Source Analysis Questions

What information from our primary source analysis should be included in our poster presentation? Is it like a scientific poster (intro, methods/sources used, “results”) or something different?

Some of the content I am analyzing is sexually explicit. Would tags on my annotated bibliographies/primary source analysis drafts be sufficient enough warning for viewers unprepared to view this content, or should I include a message within my text before sexually explicit images occur warning of what is ahead?
