If this Casey Key estate has an understated “old money” look, there’s a reason why. It was the home of the Louis Marx family, the famous toy manufacturer. Back in the 1950s, Marx was the biggest toy company in the world, credited with popularizing the yo-yo. His grandson, Louis Marx III, is the current owner.

And many older readers can undoubtedly remember those metal lithographed dollhouses from the '50s, Colonial in style and with plastic furniture. Millions were sold. Well, here’s the real house all those dollhouses paid for. 

The estate consists of a five-bedroom main house that dates to 1949 but has been renovated and is in beautiful shape. There’s also a furnished four-bedroom guest house, a saltwater pool, an elaborate thatched tiki hut, a double boathouse, and a floating dock and pool. It fronts the Intracoastal but there is deeded beach access just steps away.

The interior of the main house is coastal in feeling, with many built-ins. There’s a state-of-the-art kitchen and marble baths. The entire property is fenced and gated. The guest house, set on half an acre, can be purchased separately for $975,000.

Historical note: Marx’s daughter Patricia married Daniel Ellsberg, the military analyst who released the Pentagon Papers and set into motion a chain of events that led to the resignation of Richard Nixon. Could Patricia and Daniel have been plotting the whole thing in this very tiki hut?
