If anyone recognizes where this was published, please let me know. In the top margin, it's labeled "Illustrated Romance Library No. 71" and entitled "Treacherous Kisses," but as illustrations were often re-used, this may have appeared with a different title. It has been attributed to Jon Whitcomb, but it appears unsigned. At the very least, it seems to have appeared as a slightly reworked sepia illo as seen here .
