These floral charms vignette reminds me of a pair of earrings. They were identified as charms in the Hungarian book where they appeared. It was published in 1907. The author was Desi Malonyai (1866-1916), a Hungarian writer and art historian. He did not identify a particular illustrator though it’s clear work from several artists was included. Gutenberg puts it in the public domain in the United States. I think, repeat I think, based on his date of death (over 70 years ago), the work is in the public domain everywhere.
Both include a floral charm dangle with an outer ring of picot-like circles and a central illustration with flowers, leaves and vines. Use them together or find a great new home for just one.
