This is a tin lid to an old can of Italina Laxative Preparation. It's large for a lid, measuring 2&3/4 inches in diameter. As you can see in the photos, It shows minor wear on the top, and oxidation on the bottom, but isn't bent, and has crisp, colorful graphics. Neat general store, or vintage advertising.
I currently have several pieces of vintage advertising, including other tin, in my shop, and am happy to combine shipping. To see them all, type, "advertising" in the search box at the top of this page
