There are plenty of portraits of Queen Elizabeth, but a recently rediscovered photo from 2004 shows the monarch in a rare candid moment.

Photographer Rob Munday's snap of the monarch, titled Platinum Queen: Felicity, is going on display for the first time this week to mark the Queen's Platinum Jubilee, which celebrates her 70 years on the throne. Against a black background, the Queen wears the Diamond Diadem with a single strand pearl necklace and pearl earrings — but it's her amused expression that makes the photo stand out.

Munday explained to Hello! magazine that he was taking some test shots when the Queen's close aide, personal stylist and dressmaker Angela Kelly make a funny remark.

"The atmosphere was incredibly jovial," he recalled. "Angela Kelly is a very funny woman, very down-to-earth. And really, really nice, she put us all incredibly at ease. She would tell jokes, and she'd obviously said something funny to the Queen. And she sort of laughed at that exact moment I pushed the button to do a test shot."

He added, "Obviously the Queen is very, very comfortable with Angela Kelly, they have this incredible bond, and you can see it."
