My Grapevine Quilt

Quilt created by my Grandmother, Elizabeth O'Brian and my mother, Virginia Galbraith, both of Evansville Indiana, sometime in the late 40's. The quilt is at least 65 years old and is in mint condition. I've looked and looked but have never found anything similar to this quilt either in shops, quilt books or on the net. I am 78 years old, widowed with 4 grown children and would like some information on the quilt pattern to pass on to them. It is a full size quilt . Any verifiable information will be most appreciated. Thanks so much.
