Vintage Red Glass Espresso Coffee Cups Ruby Flash White Pattern Mid-century

Set of 4 cups with detachable metal holders. I believe they date to the 1940's. Most likely Made in France or Italy, they are marked, but I can't make it out. Excellent condition. No chips or cracks. Handles in good condition, may need polishing. A couple of small spots of wear, not immediately noticeable, most likely caused by handles rubbing. Cups measure about 2 1/2" tall and 2 3/4" in diameter at the top. Reasonable offers always welcome. I re-use shipping materials to reduce waste. BA
