・ US Navy flight cap from the 1940s. Also known as a Blue cap. Made of sturdy wool from the WWⅡ era, it's a ✨work of art✨. ・ Size is 52cm, not a large size, so rather than wearing it yourself, it's recommended for collectors, especially those collecting US Navy items. ・ Non-smoker, no pets. ・ Anonymous shipping via Rakuraku Mercari. ✨ I also have other military items listed. Please take a look! →https://jp.mercari.com/user/profile/201242476 ◆ Size: Head circumference approx. 52 cm ※ Please excuse the amateur measurements. 　Please check the photos and 　confirm at your own discretion. ◆ Frequency of wear Purchased last year and unworn.
