To mark Meghan Markle and Prince Harry’s move into Frogmore Cottage next the soon-to-be parents will receive a present from the Queen so valuable no-one else can buy it.

The royal art collection isn’t just any old paintings — it’s the largest privately owned collection in the world, made up of more than a million works from artists like Andy Warhol, Leonardo da Vinci and Rembrandt.

Getting to pick paintings from the royal art collection seems to be an honor the Queen likes to give newlyweds in the family.

When Prince William and Kate Middleton were married in 2011 they were also allowed to pick several works for their Kensington Palace and Anmer Hall homes.
