Vintage spring loaded, tin and metal, hanging or desk paper holder that advertises the "South St. Louis Dairy Co.". It has 2 pre drilled holes for hanging. The spring clip works perfectly. As you can see in the photos, there is some paint wear. No rust. Marked on the back, "B&B, St. Paul Minn. USA". It measures 3&1/2 inches tall, by 2 inches wide.
I currently have several other advertising items in my shop, and am happy to combine shipping. To see them all, type, "Advertising" in the California Girls search box at the top of the page.
