One of my favourite 20th century composers and I’ve always liked this 1934 caricature from the BBC’s Radio Times magazine, reprinted a few years ago during the Proms season. I’ve searched in vain for the identity of the artist in the hope of finding more work in this style; the “R” monogram is undoubtedly a clue. The picture also turns up on a few Bartók websites uncredited. If anyone knows the answer, please leave a comment. Meanwhile this page has some examples of more recent portraits.
