Prince Harry made a whistlestop tour back to the UK to witness his dad being officially crowned as the new King before making a swift return to the US following the Westminster Abbey service on Saturday.
The Duke of Sussex had been rumoured to be heading back to California after stopping over less than 24 hours, with the historical day for the Royals also falling on his son Prince Archie's fourth birthday.
But despite his hectic dash back home from Heathrow airport, the ex-working Royal didn't leave without a special keepsake of the landmark event.
