A colourful folk art painted domed lid tin box by Mary Grady O'Brien. I believe that Mary made the box herself. I do not know if it opens - I don't want to risk scratching the paint. Clearly signed and dated on the bottom.
3/4 inch (1.9 cm) wide, 9/16 inch (1.4 cm) deep and 13/16 inch (2.0 cm) tall.
