Just what your Instagram feed was missing: a rare vintage photo of the Kennedy family.

When it comes to the Kennedy clan, their Instagram #TBT (Throw Back Thursday) posts aren't your average.

Particularly if you're Kerry Kennedy, and your latest #TBT upload involves a sepia-toned photo of a cameraman trying to film a sailboat full of about 20 members of America's most famous family.

The niece of the late JFK added the cheeky caption, "Always room for one more!"

Always room for one more! #TBT

In recent days, the Kennedys have posted a whole host of previously unseen gems.

After her family boat shot, Kerry also shared an image of her father Bobby Kennedy with astronaut John Glenn riding the Matterhorn Bobsled at Disneyland. Both men appear to be wearing suits - ever the professionals!

Meanwhile, her brother Robert Jr. was evidently also feeling nostalgic this past week. The environmental attorney posted a black-and-white snapshot which features his and Kerry's parents, Robert F. Kennedy and Ethel Kennedy, and their massive brood of 11 children.
