Although it enjoys great popularity today, at the time when he died, Mucha's style was considered outdated. His son, author Jiří Mucha, devoted much of his life to writing about him and bringing attention to his artwork. In his own country, the new authorities were not interested in Mucha. His Slav Epic was rolled and stored for twenty-five years before being shown in Moravsky Krumlov, and a Mucha museum opened in Prague, managed by his grandson John Mucha.
Mucha's work has continued to experience periodic revivals of interest for illustrators and artists. Interest in Mucha's distinctive style experienced a strong revival during the 1960s (with a general interest in Art Nouveau) and is particularly evident in the psychedelic posters of Hapshash and the Coloured Coat, the collective name for British artists Michael English and Nigel Waymouth, and Bob Masse.
