The City Theatre in Konstanz, Germany claimed the offer is a social experiment
George Tabori's play is based on Mein Kampf and takes place on Hitler's birthday
Those who choose not to wear the swastika will be asked to wear a Star of David
German prosecutors on Wednesday cleared a performance of a satirical play named after Adolf Hitler's book 'Mein Kampf' that promises free entry to spectators who wear a swastika.
The theatre in the Bavarian lakeside town of Constance says it aims to show how easily people can be corrupted but the approach sparked numerous legal complaints.
Local prosecutors however on Wednesday said the premiere could go ahead on Friday, which marks Hitler's birthday in 1889, as well as the controversial swastika campaign.
