The bottom is inscribed with the following "Grandma Sally Spath Wehrel", who lived from 1914 to 1993 in Indiana. There is also a children's writing that says "Mother Sally", most likely written by her only child, Helen, who is my maternal grandmother. The ink pot insert is most likely made of Bakelite, due to its lack of transparency, sound when tapped, and a very light chemical smell produced when rubbed; this is one of the first plastics invented, and was highly sought after for its durability over glass. The bottom of the ink pot has a 4 leaf clover or 3-toed animal imprint, though it is unclear whether intentional or due to use over time. There is a green patina on the lid of the inkwell, indicating that this is most likely made of bronze. There are also distinct dimples indicating that the metal was hammered. This family heirloom most likely dates to the 1920s-1940s, as this is when Bakelite was most commonly used for ink pots. This appears to be a very rare item, as there was only one other match found online.
