This is a motorcycle accessory, likely used as a helmet, from around the 1960s to 1980s. It's a slightly small M size, around 57-58cm. It's vintage, so there's some dirt and peeling on the inside. It has a design similar to a Buco, but the details are unknown as it was a gift. This is being sold as a decorative interior item. Please ask any questions in the comments.
