Pastel portraits created by American folk-rock icon Bob Dylan are heading to London's National Portrait Gallery.

The musuem has announced that the exhibit Bob Dylan: Face Value, a display of 12 new works, will open later this month.

"Bob Dylan is one of the most influential cultural figures of our time," National Portrait Gallery Director Sandy Naime said in a statement.

"I am delighted that we can now share these 12 sketches which were made for display at the National Portrait Gallery."

According to the gallery, the portraits represent characters based on "an amalgamation of features Dylan has collected from life, memory and his imagination and fashioned into people, some real and some fictitious."

Though the 72-year-old music icon has sketched and painted since his youth, he has only recently begun exhibiting his personal artwork. He has previously shown his art in Germany, London, Copenhagen, New York and Milan.

Dylan, born Robert Zimmerman, has written hundreds of songs, influenced countless musicians and continues to play more than 100 concerts a year. 

Bob Dylan: Face Value will be on display Aug. 25 through Jan. 5, 2014.
