Vintage Heinz Pickle Pin Pittsburgh Green Plastic Advertising Merch Swag Ad

Hello, you're looking at a vintage pin in the shape of a pickle with the Heinz brand on it. It was likely made in the 1970s or 1980s, possibly before. It has a brass-colored safety pin to attach it to clothing, but I'm unsure of the metal used. It measures about 1.25 inches long. Condition-wise it has some discoloration on the safety pin, and a few areas of the plastic have a bit of wear, especially on the ends. Please see photos for more detail on the condition.
