Sea Chest with wood bindings, painted interior

This is a 19th century sea chest out of Pirates of the Carribbean.  It is really beautifully shaped with a rounded top and two inch wood bindings circling the chest. The wood bindings are secured with decorative metal brackets and there is a large metal lock.  This interior is heavy white paper like material painted with Scandinavian designs. Inside the heavy top, the underside is painted a deep rose with Roses painted and a heavy, maroon leather pouch attached.  I have stored blankets in it for years but it won't fit in my studio. It appears to be the real thing, is very beautiful and I can't believe it doesn't belong in a museum somewhere.
