I've made today pictures bigger than I normally do, so the detail shows more.The block is actually about 7" square. I know some of you gals like Sio have background in old fabrics or dating quilts. My guess is that the black if probably 19th century...late 1800's into early 1900's. There were several blocks "with" this one, and all have similar fabric. I'm guessing from the same scrapbag.
