No chips or cracks. Threaded hole in the middle with minimal rust. I did not measure the diameter. This vintage cast iron lollipop sign base is a unique piece of advertising memorabilia that would make a great addition to any collection. Measuring 22 inches in diameter, the red base features a nostalgic gas and oil theme, showcasing the original design from the United States. Perfect for adding a touch of retro charm to any space, this sign captures the nostalgia and authenticity of vintage advertising.
