BERLIN.- The exhibition dedicated to Frida Kahlo (1907-1954) at the prestigious Martin Gropius Bau in Berlin has received thousands of visitors each day who have waited in line for up to seven hours to enter. The exhibition, which closes on August 9, has broken records of visitors nearly every day since its opening in April, but in recent days, the lines are even longer and have a waiting period of four to seven hours. Many people wait with sleeping bags to ensure entry to the largest retrospective of the Mexican artist ever presented in Germany, which only, in the first two months, received 130,000 visitors. Once inside the museum, visitors have to wait one to two hours to access the exhibition halls. Given the huge crowd, the Gropius Bau decided to extend visiting hours until 22:00 hours. The exhibition includes about 120 works, including paintings and drawings, including a series of photographs from family archives
