I can't see the photo and I'm not an expert or even a knowledgeable rookie. What makes me question the age of the quilt is the size. Most old quilts are "full size" quilts. Most were used like blankets, between the sheet and "counterpane", as my great-grandmother would say. They were not used as a bedspread, as we use them today. They did not wash well, so all efforts were made to keep washing to a minimum. The 108" measurement sounds pretty large for an old quilt.
That's my uninformed opinion.
