Calico Wing Back Sofa Chair and Ottoman Dollhouse Parlor Set

Sweet set of three handmade upholstered pieces of dollhouse furniture. They are made of wood and cardboard covered in navy blue calico with tiny red, yellow and white flowers with green leaves. The high back sofa and chair and footstool or ottoman have padded cushion seats and ruffled pleated skirts. Each is finished with 4 brass ball feet.
Sofa measures 5” wide x 3 ¾” tall and 2” deep. Chair is 2 ½” wide x 3 ¾” tall and 2” deep. Ottoman is 1 3/4” square x 1” tall.
I am guessing they are vintage 1960’s 1970’s.
