Unusual Glass Cocktail Shaker with Square Etched Motif

Unusual Glass Cocktail Shaker with Square Etched Motif in green glass. Classic shaker style with a graduating square block treatment with squiggly lines between the squares that add a unique look to this rare piece, one I’ve not seen before. Cocktail shaker collectors seem to always be looking for something unusual, something different. Here is one that certainly falls into that category. Would look proud in any collection. The metal work is in excellent condition, bright and clean.
