Demitasse cup and saucer 1960s with iridescent Carnival glaze flawless condition

this is a lovely little teacup. charming and delicate both into design and size. The glaze is a Carnival glass type of iridescence. I think the decade might be 1950s when there was a surge of interest in demitasse and Carnival Glass. Both the saucer and the teacup are marked but I cannot discern what the markings are. smoke-free home see photos for details thank you for visiting my closet🌧🌈 Reasonable offers are always welcome Bundles are almost always discounted.
