By great coincidence I bought this set of PHQ stamp cards just a few days ago. Although they are titled "Dogs" as a series, they are all oil paintings by George Stubbs, an 18th century English (Liverpool) artist probably better known for his paintings of horses. The stamps were issued in 1991.
Early last year two of his non-horse paintings, one of a kangaroo and another of a dingo, were "saved for the nation" after they had been sold to a buyer outside the UK. Donations and lottery funding resulted in enough funding to allow them to remain in the National Maritime Museum in Greenwich. Stubbs didn't visit Australia, then known as New Holland, but created his paintings from sketches made on Captain Cook's expedition on HMS Endeavour.
