The sisters lined up in the same order back at that time. The photograph looks great and they have done so for him in the same line up ever since.

They look super confident in the summer sunshine. They are young and looking forward to a bright future.

They have ditched their casual dresses and are looking classier than ever. Although they have this confident look on their faces, they clearly have more going on in their minds.

In this shot, the photographer decided to focus more on their faces. The thought of entering adulthood and growing apart is most probably making all sisters frown.

One sister chooses pants while another chooses to opt for a more formal dress. One sister has a relaxed pose while the other one is contemplating. We can only wonder what is going through their minds.

Although they had solemn faces in the previous years, they look a bit more prepared to face the world in this picture

The sisters have a confident look on their faces; perhaps they feel more optimistic than before.

As the wind is sweeping through their hair, they look more self-assured. They look ready for another pose. By now, we know that getting all these sisters to smile is a bit of a challenge.

As they are in the middle of the field and have wind playing with their hair, each woman has a different facial expression that is reflecting something different.

Although this picture doesn’t really tell us what has happened in their lives in the past, we can only imagine it.

Although you can notice there are no smiles on their faces, the picture still shows that their bond has only grown stronger.

It looks as if each sister has made plans regarding her future and all of them look more confident.

Each sister looks into the camera with a sense of defiance, making us wonder what they’re up to next.

Perhaps, they are thinking about something good that has happened or maybe it’s a nice day.

We can assume that this year was more challenging for the sisters. Well, this is life.

Perhaps, it is because she has chosen a different path or living away from her sisters.

Is their bond fading? And we are with you if you are wondering why is it difficult for them to smile.

These sisters show us that no matter what happens in their family, they will still get together for a photo.

Nevertheless, the smiles are back and it looks great to see them look supportive.

Nixon was not present at that time and it is unclear why.

The sisters look like they want to spend more time in each other’s company. This also appears to be the happiest picture of the sisters.

One must admire that all the sisters are still dedicated to the annual tradition.

Three of the sisters’ expressions show that there is something more behind the photo.

Why these sisters have a gloomy mood most of the times? Well, it is a mystery.

They look like warrior sisters. The picture shows they are more determined than ever to stay strong.

The picture gives a strong message from the sisters that they have not given up on each other and want to uphold the bonds.

Their poses show that they are enjoying their time relaxing on the beach. However, it still seems like a big challenge to make them all smile.

It seems quite clear that she has all their respect and love.

One of the amazing things about this project is that we are allowed to see their lives without the need to get to know them.

It seems clear to the viewers that the sisters are not much concerned about appearance.

If you haven’t noticed so far, two sisters have almost the same pose in each photo while the other two always a different pose.

Just like last year’s picture, one sister decides to look away. She isn’t smiling as well while others have shy smiles for us.

They have stayed together all these years as strong women who have always strived to stay confident.

It is not hard to imagine that each sister has a different personality. However, they are still together and that’s what is important.

Even in this picture, we can see that all three sisters gravitate towards Bebe.

It also shows that each sister is equally involved in contributing to this world-famous series.

Even this is a black and white photo, but their beautiful relationship with each other is filling the photo with colors.

That’s what the photographer Nicholas Nixon said: “There are four people I would like to thank: the Brown sisters themselves. These pictures grew out of my curiosity about and admiration for this band of beautiful, strong women, who first let me into their lives, then allowed me to try making one picture, then joined me in a tradition, an annual rite of passage. I love my sisters-in-law Mimi, Laurie, and Heather, and I thank them wholeheartedly for their love and patience. Bebe, my true love, my best friend, is the center of my life. How lucky, how grateful I am.”

Nicholas Nixon’s The Brown Sisters Series opens 1st April at Sotheby’s New York.

Who knew it would turn out to be a series that is estimated to fetch $200/300,000.

We can see how much these sisters have grown old over all these years and yet they still look super strong.

What is more important here is that they have come this far and still kept the annual tradition alive.

At the time this photograph was taken, the ages of sisters were: 56, 64, 66, and 68.
