Here is the front, which is what I could see in the auction photo. The half square triangles are about 1/2 inch in size. You can see a little Prussian blue, some green and a touch of cheddar. Some of these fabrics date to ca. 1850, but others appear to be late 19th century. I would date the piece to around 1890.
The front is all I could see in the on-line auction, so when I received the quilt and looked at the back, I had a nice surprise. A date in cross-stitch, 1892.
The back is a crazy quilt piece with much of the silk fabric lost. From what I can read, it says
aged 68?? (the 8 is clear to me but what do you think the other number is?) 1892.
