Portrait of a Man with a Glove or Portrait of a Man Holding a Glove is a 1640 painting by Frans Hals. The subject of the painting is unknown but believed to be a physician partially due to the painting previously having been called Portrait of a Doctor. The portrait demonstrates Hals' "rapid spontaneous manner of painting".[1] It was acquired in 1764 by the Hermitage Museum in Russia.[2] It was previously owned by Frederick the Great, who sent it to Catherine the Great as part of a batch of paintings in lieu of paying off several debts to Russia.[3]
