Northwood Glass started producing the Acorn Burr pattern in opalescent first then Carnival Glass.  This Covered Butter Dish is a stunning piece of vintage American glassware. With its round shape and marigold color, it features a decorative acorn burr pattern that adds a touch of Edwardian style to any table setting. The butter dish is made from high-quality glass and has a glossy finish. It is an original piece with an impressed backstamp, and it comes from the production line of the acorn burr pattern. The dish has a normal capacity and is perfect for serving butter at any meal. The item length, height, and diameter can be seen in the pictures, making it easy to get an idea of its size. This antique piece is a must-have for collectors of historic glassware, especially those who love carnival glass.  I found no damage other than normal ware---the base has deeper color than the top but both have wonderful rainbow hues.
