Hailed in his time as “the greatest living Australian,” Barry Humphries (who died in 2023, aged 89) was a Renaissance figure of Rabelaisian sensibility: actor, comedian, columnist, aesthete, and, most famously, the creator and impersonator of that unsinkable royal barge, Dame Edna Everage. We shall not see her likes again, but, listen up, possums, a few artifacts of her reign will be up for auction at Christies, such as Dame Edna’s diamante-encrusted Sydney Opera House glasses. Perhaps the real enticements, however, are the items from Humphries’ collection of Oscar Wilde-iana, including Wilde’s signed copy of Salome, a first edition of The Importance of Being Earnest, and Max Beerbohm’s original ink portrait of the Divine Oscar. —James Wolcott
