Numerous white and yellow hard hats can be seen in the film when Bond visits a pipeline construction site. This hat is made from sturdy white plastic, and features a sticker on the front with the King logo: "K."
This standard issue construction hat would have fit over the actors head with an adjustable inner plastic strap. The hat is made by Johnson Safety Products in Oxford England and includes a stamp in the plastic, just under the brim. It measures approximately 8.5" x 7.5" x 11" (22cm x 19cm x 28cm) and shows wear from production use (see photos) but is otherwise in good condition.
This item comes with a Prop Store Certificate of Authenticity.
