I'm guessing this is an embedded graphic. I received a packaged file for print, all is fine, but I'm pondering the "image" shown. (I was curious how they formatted the rules and type and started selecting)
After removing everything else from the document, Find Font show no fonts used; the links panel is empty; info for the frame lists nothing; it is not outlined type. One layer; show hidden characters is on.
The file package report lists Links and Images: 1 link (a stock photo used on page 1), 0 missing, 0 embedded.
