Early 1900's Handy Sewing Kit, Boot Shaped Case

This boot shaped "Handy Sewing Kit," likely dates from the 1920s to 1940s. The boot is made of black faux-leather and has red laces and a snap closure. There is noticeable wear and some fragility, but overall, it is in good antique condition—please refer to the photos for details. Inside the boot are three small wooden spools of thread and a piece of flannel; one spool is tucked into the toe and more difficult to remove.
