A few months ago I saw this quilt for sale in an online auction.
It didn't last very long but I copied the photos.
On the back you can see that each of the blocks was quilted and bound before being set together, what we today call potholder quilts. This technique was done during the Civil War by sewing groups making quilts for soldiers---but you also see it in other eras.
Could it be a Civil War quilt
made between 1861 and 1865?
A look at the overall quilt tells me no for a couple of reasons
1) That crazy quilt block in the lower corner below---not done till the 1880s.
2) That large scale black or navy blue print looks wrong for era too.
But this block makes me think there is some Civil War connection.
Here we have four Union shields
Very much like a quilt with repeat blocks of four Confederate shields. It's an unusual pattern.
Perhaps the blocks were begun during the War and finished later. One could just keep adding finished blocks....
