(CBS News) - Former first lady Nancy Reagan turns 91 Friday.
Reagan appeared at the Reagan Presidential Library Thursday, hosting an exhibit from the Walt Disney Archives. It was her first public appearance since a fall in April left her with broken ribs.
Reagan joined Robert Iger, chairman of the Walt Disney Company, to open the exhibit. Perhaps it wasn't the kind of birthday greeting a 91-year-old might expect, with Mickey and Minnie Mouse serenading the former first lady with "Happy Birthday."
