Here's a slightly nicer Grommet-Web example that sold on eBay. It's a higher end adult model, as evidenced by the quality leather and the thicker, more substantial piping around the wrist strap and finger opening on the back.
Experienced Seller is indeed saying "1920s", and was asking $99 but I'm guessing it actually sold somewhere in the $75 range. In addition to being a high-end model, the condition is better on this one, with no holes and a smoother inner lining. After clicking the link directly below, click on "See Original Listing"....
