NEW YORK (CBSDFW/AP) — For the last 18 months, Former President George W. Bush has spent time painting and writing a book honoring American immigrants.

Bush’s “Out Of Many, One: Portraits of America’s Immigrants” includes 43 portraits by the 43rd president.

“Today, I’m pleased to announce a new book and exhibit at @thebushcenter honoring new Americans who have contributed to the cultural richness, economic vitality, entrepreneurial spirit, and renewed patriotism of our country. As I said from the Oval Office in 2006, ‘America can be a lawful society and a welcoming society at the same time’,” Bush wrote in an Instagram post.

They are four-color paintings of immigrants he has come to know over the years, along with biographical essays he wrote about each of them.

For the past 18 months, I’ve been painting the portraits and writing the stories of 43 immigrants I have come to know. Today, I’m pleased to announce a new book and exhibit at @thebushcenter honoring new Americans who have contributed to the cultural richness, economic vitality, entrepreneurial spirit, and renewed patriotism of our country. As I said from the Oval Office in 2006, “America can be a lawful society and a welcoming society at the same time.” Available for pre-order now and debuting March 2, 2021, my hope is that OUT OF MANY, ONE will help focus our collective attention on the positive effects that immigrants have on our country.

Bush, who served as president from 2001-2009, has often praised the contributions of immigrants, a notable contrast to President Donald Trump.

As president, Bush supported a bipartisan immigration reform bill that narrowly failed to pass in 2007, with opposition coming from both liberals and conservatives.

The book is currently available for pre-order and debuts March 2.
