Together with Vienna and Budapest, Prague became an internationally-known centre for opera at the end of the nineteenth century, a reputation which it has retained ever since. It was the opening of the Národní Divadlo (National Theatre) in 1881 that provided the showcase venue for operas old and new, and many of Jaroslav Štika’s clients would have been very familiar with the tally of operas included in this erotic portfolio. It was one of his most popular and widely reproduced albums.
