This Westmoreland glass Argonaut Shell pattern amethyst carnival colored lid measures approx. 5.25" across the bottom or base of the lid. This piece fits the 3 legged/footed compote bowl. It would look great on the white bottom or the purple marble bottom. Excellent condition with no chips or cracks -- nearly perfect. I see the WG mark on the underside. I left the handwritten sticker from the liquidated shop that this came from. A beautiful lid! I'm always happy to combine shipping to save you money (ask me for a quote). I accept checks, money orders, Paypal, and Google Checkout.
