Although the Tate Britain exhibition Aubrey Beardsley, with 10 exceptional drawings from Princeton University Library, has now closed due to CV19, the museum has posted an interesting video discussion here:

“Curator Stephen Calloway and drag performer Holly James Johnston sit down to tea to discuss the ‘dos and don’ts’ of dandyism according to artist Aubrey Beardsley. Beardsley shocked and delighted Victorian London with his black and white drawings. In fact, the 1890s even became known in some circles as the ‘Beardsley Period’. At the centre of this decadent world was the ‘dandy’, an elegant and enigmatic character made famous by Beardsley and friends like Oscar Wilde. You can find out more about Beardsley in an exhibition of his work at Tate Britain, from 4 March to 25 May 2020: http://bit.ly/3cjrc75 “

Even today, Aubrey Beardsley drawings shock and delight. Here are a few of our drawings sent to London and currently safely “covered in place” on the Tate walls. https://graphicarts.princeton.edu/2020/01/14/aubrey-beardsleys-die-gotterdammerung/
