I always wanted to steal a valuable artwork as a kid, and hang it on my wall. I wasn't really into art, and still am not. I wasn't looking for profit. I just wanted to defeat a large system and walk out with something that was "my little secret," that I could look at every morning and think of how I outwitted the system.
Still a thought I have at the back of my head sometimes. Obviously wouldn't do it.
In 2000, Claude Monet's Beach in Pourville was stolen from the National Museum in Poznań, Poland. The police suspected a steal-to-order gang.
Six years later, an unemployed bricklayer was fingerprinted for not paying alimony to his ex-wife. His fingerprints matched those left in the museum, and the police found the painting behind a wardrobe in his apartment. He told the court that he fell in love with the painting when visiting the museum and wanted to have it all to himself[0].
You might be interested in the novel "The Goldfinch". It's pretty relevant to this post, and somewhat relevant to your comment. But it isn't a heist so to speak.
