Textile Sample from Sample Book

The image shows a square piece of fabric with a yellow background. The fabric is dark purple with a pattern of lighter purple and black. The pattern appears to be a mottled design with irregular shapes. A white rectangular label is attached to the bottom left corner of the fabric. The label has black text that reads "3475" in a vertical orientation. The fabric is set against a yellow background with small black speckles. The background appears to be a flat surface, possibly a table or countertop. The image is likely a textile sample from a sample book by an unknown artist.
