Mid Century Hand Knit Vintage Four Leaf Clover Cardigan Sweater, Size S/M, Pewter Buttons, Nordic?

Description - Very cool hand knit cardigan sweater with four leaf clover stripe design. It has big pewter buttons up the front that have flowers on them. This one is hard to date because it's handmade but my best guess is from some point between the 40s and 60s
