en.wikipedia.org/wiki/Audrey_Hepburn

UNICEF’s official Audrey Hepburn profile identifies her as a “UNICEF Goodwill Ambassador from 1988 to 1993.” The same page also says, “Soon after becoming a UNICEF Goodwill Ambassador in 1988, she went on a mission to Ethiopia.” That directly contradicts the infobox date range beginning in 1989. The start year should be 1988, so the correct service range is 1988–1993.

This sentence gives the wrong appointment year. UNICEF’s official Audrey Hepburn biography says she was a “UNICEF Goodwill Ambassador from 1988 to 1993” and adds that “Soon after becoming a UNICEF Goodwill Ambassador in 1988, she went on a mission to Ethiopia.” Because UNICEF itself places her appointment in 1988, the article’s statement that she was appointed in 1989 is incorrect.
