Childs/Salesman's Sample Rocking Chair

This came from my Grandmas house many years ago. She bought it from an antique store in the late 60's. At first I thought it was a child's rocking chair but, the more I look at it, maybe it's a salesmans sample?? Any thoughts on the age and possibly what it could be would be appreciated. The height is 22 1/2 inches and the width is 13 1/2 inches. t
