Kirchherr admitted she was not good at business because of insufficient organisation, and had never really looked after the negatives of her photographs to prove ownership. Her business partner Ulf Krüger—a songwriter and record producer—successfully found many of Astrid's negatives and photographs and had them copyrighted, although he believes that Kirchherr lost over the years because of people using her photographs without permission. In July 2001, Kirchherr visited Liverpool to open an exhibition of her work at the Mathew Street art gallery, which is close to the former site of The Cavern Club. She appeared as a guest at the city's Beatles Week Festival during the August Bank Holiday. Kirchherr's work has been exhibited internationally in places, such as Hamburg, Bremen, London, Liverpool, New York City, Washington D.C., Tokyo, Vienna, and at the Rock 'n' Roll Hall of Fame.
