Lindsay is buried in Springwood Cemetery in Springwood, close to Faulconbridge where he lived.
A large body of his work is housed in his former home at Faulconbridge, New South Wales, now the Norman Lindsay Gallery and Museum, and many works reside in private and corporate collections. His art continues to climb in value today. In 2002, a record price was attained for his oil painting Spring's Innocence, which sold to the National Gallery of Victoria for A$333,900.His frank and sumptuous nudes were highly controversial. In 1940, Soady took sixteen crates of paintings, drawings and etchings to the U.S. to protect them from the war. Unfortunately, they were discovered when the train they were on caught fire and were impounded and subsequently burned as pornography by American officials. Soady's older brother Lionel remembers Lindsay's reaction: "Don't worry, I'll do more
As a break, he would work on a model ship some days. He was highly inventive, melting down the lead casings of oil paint tubes to use for the figures on his model ships, made a large easel using a door, carved and decorated furniture, designed and built chairs, created garden planters, Roman columns and built his own additions to the Faulconbridge property.
In 1938, Lindsay published Age of Consent, which described the experience of a middle-aged painter on a trip to a rural area, who meets an adolescent girl who serves as his model, and then lover. The book, published in Britain, was banned in Australia until 1962.Wikipedia
