Vintage Ivory Crochet with Butterflies Doily

Pretty vintage doily in ivory crochet. Lacey and airy with pretty butterflies. It measures about 30" x 13". Looks and feels like cotton or linen to me and my best guess as to age is circa the 1950s or 1960s. Has been gently laundered and ironed by yours truly.
Excellent vintage condition. I spotted one bit of foxing on the back of a butterfly.

Please note that many of my items are vintage and/or made using vintage materials. I do my best to list any major issues but some signs of life and love are to be expected and only add to their charm.
