Rare old El Paso Margarita Glasses Cactus "Old El Paso" is a top brand of Mexican Tex-Mex ingredients with a history of nearly 100 years. These are Old El Paso margarita glasses that I couldn't find when I searched. I think they are quite a rare item. How about a set of 4? The age is unknown. Please purchase only if you understand that these are old items and have an appreciation for antiques.
