The portraits of President Barack Obama and Michelle Obama have become a destination for visitors to the Smithsonian’s National Portrait Gallery in Washington ever since they were unveiled in 2018. Next year, the acclaimed paintings — by the artists Kehinde Wiley and Amy Sherald — are going on the road with a five-city tour that the museum announced on Thursday.

“The portraits are going to be shared with people who did not have the opportunity to see them,” Ms. Sherald said in a telephone interview, adding that for some, visiting the paintings has been something of a “pilgrimage.”

In mid-May 2021, the portraits will temporarily come down from the walls of the Portrait Gallery, which is also publishing a book — “The Obama Portraits” — in partnership with Princeton University Press, to be released Feb. 11.

The tour will start at the Art Institute of Chicago in June 2021 and continue through May 2022 with stops at the Brooklyn Museum; the Los Angeles County Museum of Art; the High Museum of Art in Atlanta; and the Museum of Fine Arts, Houston.
