1959 Sofa and Chair set by Gardner Craftsmen, Inc.

Looking for any value information on this set.

I have a green vinyl couch and chair set manufactured by a Massachusetts company called Gardner Craftsmen, Inc. The date that is wood burned into the frame of couch says 1959.

The condition is really nice. The legs are little wobbly and could use some tightening. No tears or rips and the springs still keep their shape. They are really stunning pieces for what I am assuming are 56 year old pieces of furniture that are is still in use.
