The official portraits of former President Barack Obama and first lady Michelle Obama were unveiled Monday at the Smithsonian's National Portrait Gallery in Washington, D.C.

The Obamas applauded and cheered as the works of art were revealed Monday morning, first Michelle Obama's portrait, then the president's portrait.

"How about that? That is pretty sharp," the former president said.

The former Democratic president's portrait was painted by Kehinde Wiley, who is known for his vivid, large-scale paintings of African-Americans.

The former first lady's painting was done by Amy Sherald, a Baltimore-based artist who won the Gallery's 2016 Outwin Boochever Portrait Competition.

"As you may have guessed, I don't think there's anybody in my family who's had a portrait done, let alone a portrait that will hang in the National Gallery," Michelle Obama told attendees.

"I am a little overwhelmed, to say the least," she added. "I am humbled. I am honored. I'm proud, but most of all, I am so incredibly grateful to all of the people who came before me in this journey — the folks who built the foundation on which I stand."

Wiley and Sherald became the first African-American artists to paint a presidential couple for the Smithsonian Institution.

"These portraits will live to serve those millions of future visitors looking for a mentor, some inspiration and a sense of community," National Portrait Gallery Director Kim Sajet said.

Former Vice President Joe Biden, movie director Steven Spielberg, actor Tom Hanks, and other celebrities attended the ceremony along with the former first couple.

The museum is famous for its complete collection of presidential portraits, which it began collecting 25 years ago.

The Obamas chose Wiley and Sherald from between 15 and 20 of the museum's recommended artists.
