This 1950s beach cottage was part of a Decorator Showcase in Kennebunkport, Maine.
Cottage Home Designs decorated this cottage, called "Sea Worthy." You can see the rest of the photos on their website or rent the cottage here.
P.S. I'm on a 1950s kick today--I'm showing a 1950s kitchen on my other blog, Hooked on Houses. It has very little in common with this one, though!
