Aunt Matilda loves the Bat Key Hanger so much that she knows that she is super lucky to have two of them! Given to her by the Marback family from outside of San Antonio. It is a little known fact that this extremely wealthy family made money in Texas before oil was discovered. They did this by using bat fecal matter for amazing fertilization tools and even gunpowder for both the Civil War and World War I! Aunt Matilda uses one cast iron Bat Key Hanger to hang her key on and the other, which is mounted in her boudoir with favorite jewelry hanging from it.
