Vintage Selvedge Blueline Denim Fabric 57x40" Redline Dark Wash Large Piece NOS

Swatch of unused selvedge denim with blue selvedge line, reminiscent of older denim like levi's. Not sure the manufacturer of the denim. This denim is dark wash, and measures roughly 57" x 40". Reach out with any questions. Would be great for anyone looking to make their own stuff with selvedge denim or for repairs
