C. 1860 from SE Pennsylvania.
Caesars Crown is not a very common pattern due to the difficult curved piecing involved in the design. YES, you read that correctly, the block was generally curved pieced not appliqued. In finding a few more to add to my collection, I was surprised to find that it was used as a signature quilt pattern in the 1840s and 1850s and even a century later in the 1940s and 50s.
Detail of a signature Caesar's Crown quilt from Berks and Montgomery Counties in Pennsylvania, Dated 1851 and the names and inscriptions were written by a paid professional scrivener and he signed one of the blocks- Edwin G. Fritz. German community. I'd love to find some other signature quilts or frakturs, birth announcements etc. signed and written by him. Starley antique collection.
And here is one more. It is also a signature quilt (top) dated 1850 and likely also from Pennsylvania.The writer on this one was a likely from a German community.
