old antique lace edging w/ Irish shamrock clover, 18 yards new old stock sewing trim

Beautiful early 1900s vintage ecru cotton thread lace of European manufacture... we would have guessed this was French, but with the clover design, we're thinking perhaps Ireland?

It's out of the estate of a textile dealer and collector, but sadly she left no notes on the history of her collection.

It's 1 1/2" deep x 18 yards, in excellent, unused condition. There's a few small foxing spots throughout.
